Poke him in the eye for web site

"For a character living in two dimensions, grasping the idea of life in 3D can be tough - especially if the character in question is Homer Simpson. But one Halloween episode of 'The Simpsons' forces him to confront the concept, and gives viewers a mathematical workout too.

"... Meanwhile, in Springfield, Professor Frink is giving Chief Wiggum and others an impromptu introduction to the mathematics of higher dimensions, in order to explain what happened to Homer when he disappeared through a portal. Of course, the notion of a third dimension is baffling from Chief Wiggum's two-dimensional perspective, so Frink draws a diagram:

Professor Frink:

"Here is an ordinary square."

Chief Wiggum:

"Whoa, whoa! Slow down, egghead!"
