1856

Golly, mathematicians are such a wacky bunch! You didn't think they spent all that time doing boring proofs for nothing, did you?

I love the teacher's fist throughout this. There's no good way to draw extremities on a stick figure: hands and feet are necessarily at a much greater level of detail than the rest of the body. A better cartoonist would have foreseen this as a problem and figured out a way around it, either by writing or drawing differently. Randall, being a hack, decided instead to just put these adorable weird blotches at the end of the teacher's arm. This is reminiscent of 1544, where we get this weird attempt to convey a sense of gravity by dramatically zooming in on the blank, expressionless circle-face of a stick person.

The post-punchline dialogue in the last panel is atrocious, too. No joke is ever improved by appending crappier backup jokes.
