:: I disagree, I must have seen 5 or 6 crazy "citation needed"s in recent memory, and for me it never stops being funny. :) A couple of faves have been that a baby could not plan and execute a jewel heist [citation needed] and 5 million years is longer than the average lifespan [citation needed]. :) I might have to start collecting these.

"I'm finally in the right one," made me laugh more than usual. It added character to Offscreen Student #2, something that the comic usually lacks [[User:HisHighestMinion|HisHighestMinion]] ([[User talk:HisHighestMinion|talk]]) 03:56, 29 June 2017 (UTC) | "I'm finally in the right one," made me laugh more than usual.

According to https://en.wikipedia.org/wiki/Constructive_proof "existence proof" means a non-constructive proof. Such proofs are annoying to some mathematicians as they claim existence of something but do not show how to find it. So I fully understand the teacher that she wants to grab a sword and finally find it.

To me, the comic reads (especially with the title text) with the implication that the teacher is encouraging the students to help her actually fight real numbers in real life, as if the platonic idea of numbers was "realer" than we think.

− | The sentence "There exists some number x such that f(x)=G(f(0))=1." boils down to "There is an x such that f(x)=1". The part with G(f(0)) is only a way to arrive at 1. For some reason there is an x that satisfies f(x)=G(f(0)), and since G(f(0))=1, it is equivalent to f(x)=1. | + | The sentence "There exists some number x such that f(x)=G(f(0))=1." boils down to "There is an x such that f(x)=1".
