}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
This comic presents a brief retelling of the {{w|Trojan Horse}} story, the climactic event of the legendary {{w|Trojan War}}, one of the best-known epics of ancient Greece and Rome. The retelling is a {{w|feghoot}}, set up to deliver the pun in the title text as well as a deconstruction of the story, replacing the epic elements with far more ordinary ones while keeping the tone of the tale the same.&lt;br /&gt;
&lt;br /&gt;
The premise is that the Trojan Horse story's origin is mundane. The gift to the Trojans by the (supposedly) departing Greek army, we are told, was a normal-sized, living mare, which promptly and unexpectedly dropped (i.e. gave birth to) a foal. According to the title text, this is the story of the &amp;quot;Foal of Troy&amp;quot;, which &amp;quot;history imperfectly recorded&amp;quot;. In the &amp;quot;imperfect record&amp;quot; (i.e. the {{w|Epic Cycle}} and later works based on it which tell the story of the entire Trojan War), the normal-sized live horse became a colossal wooden statue that &amp;quot;dropped&amp;quot; a commando unit of some 40 Greek soldiers, who opened the gates of Troy to the main Greek force (who had sailed back under the cover of darkness), resulting in the &amp;quot;''Fall'' of Troy&amp;quot;. The pun is implicit, as &amp;quot;Fall of Troy&amp;quot; does not appear in the comic. &amp;quot;Fall&amp;quot; and &amp;quot;foal&amp;quot; share the initial consonant and stem vowel in Ancient Greek (''πτῶσις'' vs. ''πῶλος''), whilst spelled even more similarly in English as well as being nearly {{w|homophone}}s.&lt;br /&gt;
&lt;br /&gt;
It is not made clear whether the gifter of the horse knew of/suspected the pregnancy or whether they would have even chosen to hand it over under different circumstances. However, it is consistent with the story, and with the &amp;quot;{{w|Beware of Greeks bearing gifts}}&amp;quot; trope that originated with it, that the Greeks intentionally gifted a pregnant mare to annoy the Trojans. Surprise foals, where a mare is purchased with a hitherto unknown pregnancy, actually occur. The pregnancy is typically excused as weight gain, up until the point where a foal is discovered with its mother in the morning. Horses with rounder builds, like some pony breeds, are known for maintaining undetected pregnancies. The reason a surprise foal might be salient for the comic, beyond the &amp;quot;Foal of Troy&amp;quot; pun, is the non-trivial costs of horse ownership, which can amount to hundreds or thousands of dollars per month. Food costs are part of (but not all of) this, as the comic touches on.&lt;br /&gt;
&lt;br /&gt;
The humor in the joke comes from an anachronistic assumption — that a pregnant mare would be seen as a costly burden rather than a generous gift. In reality, during the time period referenced, horses (particularly one as large as the mare depicted in the comic) were highly valued for labor, transport, and even as a food source if necessary. Far from being an unwelcome expense, such a gift would have been considered a significant and practical boon. The joke plays on the incongruity of projecting modern attitudes backward, pretending that horses were once the kind of liability they are now. Furthermore, based on how Cueball calls the offspring an &amp;quot;inner horse&amp;quot; instead of a foal (the term for a child horse), the fact that he interprets the foal's interest in oats (even though foals suckle their mother's milk for the first 8-10 months before weaning to solid food) as an attack upon Troy's food supply even though all horses need to eat but are nonetheless considered useful by humans, and his overall surprise that the mare gave birth, it seems that he does not know very much about horses. Calling a foal an &amp;quot;inner horse&amp;quot; would be analogous to calling a baby an &amp;quot;inner human&amp;quot;, thus reflecting a lack of knowledge of placental mammalian reproduction similar to [[441: Babies]].&lt;br /&gt;
&lt;br /&gt;
Archaeological evidence of a military conquest of {{w|Troy}} during the Bronze Age, or even of a major war centered on the city, is lacking. Far better evidence exists for the destruction of several iterations of the city by earthquakes. Possibly, the Trojan War legend arose as visitors attempted to explain the ruins of an earthquake-ravaged, deserted city. The &amp;quot;Foal of Troy&amp;quot; story, therefore, need not include a Greek conquest of Troy, or even a major military conflict with the Greeks.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
This comic depicts a classroom, likely relating to geography, geology or history, in which the teacher ([[Miss Lenhart]]) is discussing the similar coastlines of Africa and South America, and the way that modern understanding has revealed the cause. [[Cueball]] initially assumes that one coastline plagiarized the other before Miss Lenhart continues by revealing that it was {{w|continental drift}} that explained the similarity.&lt;br /&gt;
&lt;br /&gt;
Continental drift is the widely accepted theory that Earth's continents were once all connected, and have been moving relative to each other due to {{w|plate tectonics}}. One of the clues that actually led to this discovery was that the shapes of the coastlines of South America and Africa that are separated by the Atlantic Ocean are similar. The similarity is much greater for the submerged {{w|continental shelf|continental shelves}} than for the visible coastlines; they're like adjacent pieces of a jigsaw puzzle.&lt;br /&gt;
&lt;br /&gt;
{{w|Plagiarism}} is the act of claiming credit for another individual's work, usually by duplicating the results. The discovery of plagiarism in an already-renowned body of work is often cause for scandal, and Cueball's reaction to the assumed plagiarism of the African/South American coastlines reflects this. Of course, continents are inanimate objects, and have no concept of plagiarism, let alone know how to perform it{{Citation needed}}. It would take an extremely broad definition of plagiarism for this to count as such, based on neither continent giving &amp;quot;credit&amp;quot; to the other. That would apply equally well (or poorly) any time a thing was broken into pieces large enough that they could be fit back together.&lt;br /&gt;
&lt;br /&gt;
The title text continues the joke about plagiarism. Additional corroborating evidence of continental drift is that there are similar species of plant and animal fossils on the two sides of the Atlantic, dating to the time when they were connected (which, contrary to Randall's claim, is actually the Triassic period, not the Cretaceous). Cueball thinks that the progenitors of these species also plagiarized each other, as opposed to the more mundane explanation which is that the progenitors were the ''same'' for both. The younger fossils are descendants of some species that existed across the once-connected lands, the older ones ''are'' the species that did not yet have the nascent Atlantic Ocean in their lives.&lt;br /&gt;
&lt;br /&gt;
This is a very rare example where it is not Miss Lenhart that makes a joke as the teacher, but actually teaches the truth, and it is instead here one of her pupils that makes the joke (intentionally or not). A much more typical scenario for her teachings could for instance be seen in [[1519: Venus]].&lt;br /&gt;
&lt;br /&gt;
The theory of continental drift was originally proposed by Alfred Wegener in 1912, based on such fossil evidence and other geological features common to the two continental borders, in addition to the similarities in shoreline shapes. It's significant to the history of science as a general subject, as a proposal that was originally met with strong opposition (not to mention mockery) but eventually became accepted by almost everyone. Modern cranks and crackpots sometimes point to it in support of their own implausible &amp;quot;theories&amp;quot;, as though universal rejection of a &amp;quot;theory&amp;quot; by all of the experts somehow proves that it will someday be accepted and its originator proven right all along.  In fact, Wegener's original theory did have a serious flaw, in that it lacked a plausible mechanism, though it was otherwise correct. Modern cranks' &amp;quot;theories&amp;quot; generally lack both plausible mechanisms ''and'' good analysis of supporting evidence. (&amp;quot;Yes, they laughed at Galileo... but they also laughed at Bozo the Clown.&amp;quot;)&lt;br /&gt;
&lt;br /&gt;
The title text of [[2690: Cool S]] jokes about a milder version of plagiarism for the discovery of DNA, specifically copying off of the student in front of you.&lt;br /&gt;
