Laurel sent me this gem1, which lead me to find the wikipedia page on Mathematical Jokes:


A Dozen, a Gross, and a Score,
plus three times the square root of four,
divided by seven,
plus five times eleven,
equals nine squared and not a bit more.

And from there, I found another:

\int^{\sqrt[3]{3}}_1 \! z^2\, \mathrm{d}z \cdot \cos \frac{3\pi}{9}=\log \sqrt[3]{e}

Integral z-squared dz
From 1 to the cube root of 3
Times the cosine
Of three pi over 9
Equals log of the cube root of e.
