&lt;br /&gt;
==Explanation==&lt;br /&gt;
Here we have [[Cueball]] and [[Megan]] discussing {{w|geology}} and the words they use are ripe with puns and {{w|double entendre}}s which also have sexual meanings. In the end, they just decide to get it on.&lt;br /&gt;
&lt;br /&gt;
Specifically, the suggestive terms are &amp;quot;{{w|Bed (geology)|bedding}},&amp;quot; &amp;quot;{{w|Extensional tectonics|spreading}},&amp;quot; &amp;quot;{{w|friction}},&amp;quot; &amp;quot;{{w|Cleavage (geology)|cleavage}},&amp;quot; &amp;quot;deeper in the {{w|rift}},&amp;quot; &amp;quot;{{w|orogeny}},&amp;quot; (perhaps a {{w|portmanteau}} of {{w|orgy}} and {{w|erogenous}}), &amp;quot;huge,&amp;quot; and &amp;quot;{{w|Thrust fault|thrust}}.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
The technical terms are:&lt;br /&gt;
;Bedding : The division of usually {{w|sedimentary rock|sedimentary rocks}} into distinct layers.&lt;br /&gt;
;Spreading : A process in which two geological regions are moving apart, and potentially allowing for {{w|magma}} to rise between them. Spreading occurs in {{w|mid-ocean ridge|mid-ocean ridges}} and in {{w|rift valley|rift valleys}}. &lt;br /&gt;
;Friction breccia : {{w|Breccia}} is a rock made of broken fragments of other rocks. When these fragments can be formed from the rubbing between rocks in a fault, it is a friction breccia.&lt;br /&gt;
;Flow cleavage : The {{w|crystal|crystals}} in a rock can be aligned by the {{w|plastic flow}} of a rock when it is hot. This causes the rock to split (cleave) along particular planes.&lt;br /&gt;
;Rift : A result of spreading is that rocks break, forming vertical faults, and allowing regions to sink and form valleys.&lt;br /&gt;
;Orogeny : The process of mountain forming, or a period in which mountains are formed.&lt;br /&gt;
;Thrust fault : A sloping crack in the rocks at which one region of rocks is pushing another up.&lt;br /&gt;
&lt;br /&gt;
So it seems that Megan tells Cueball to ignore the layers in the rock, as there is evidence that the valley they are in is a recent rift valley. It was formed in cracking following the lifting up of the surrounding rocks.&lt;br /&gt;
&lt;br /&gt;
The title text is a wordplay, as it could sound like &amp;quot;nice butt&amp;quot;. {{w|Gneiss}} is a type of {{w|metamorphic rock}} made up of different bands, and a {{w|butte}} is an isolated hill with steep sides and a flat top that is smaller than a {{w|plateau}}. However, &amp;quot;butte&amp;quot; is not pronounced as &amp;quot;butt&amp;quot;, but more like &amp;quot;byoot&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Two people are doing a geological survey in a rock-strewn landscape. Megan pointing off at the ground, wearing a fedora, Cueball apparently comparing a paper/map with another patch.]&lt;br /&gt;
:Megan: Forget the bedding - we were wrong about the whole valley.&lt;br /&gt;
:Cueball: The spreading is recent.&lt;br /&gt;
&lt;br /&gt;
:[Close up on the figures: Megan in a thoughtful pose, Cueball turned her way.]&lt;br /&gt;
:Megan: See the friction breccia?&lt;br /&gt;
:Cueball: Oh - flow cleavage!&lt;br /&gt;
:Cueball: Deeper in the rift.&lt;br /&gt;
:Megan: Deeper.&lt;br /&gt;
:[An idea pops into Megan's head.]&lt;br /&gt;
&lt;br /&gt;
:[Megan also turns to Cueball.]&lt;br /&gt;
:Megan: This orogeny&lt;br /&gt;
:Cueball: is driven by a&lt;br /&gt;
:Megan: ''huge''&lt;br /&gt;
:Cueball: ''thrust'' fault&lt;br /&gt;
&lt;br /&gt;
:[They both drop to the ground, off-panel, leaving only Megan's tumbling hat and a vocal effect.]&lt;br /&gt;
:The couple: MMM&lt;br /&gt;
:[Down from comic]: Geology: Surprisingly erotic.&lt;br /&gt;
