Lisa: Well, where's my dad?

Frink: Well, it should be obvious to even the most dimwitted individual who holds an advanced degree in hyperbolic topology, n'gee, that Homer Simpson has stumbled into...[the lights go off] the third dimension.

Lisa: [flips the light switch back] Sorry.

Frink: [drawing on a blackboard] Here is an ordinary square....

Wiggum: Whoa, whoa--slow down, egghead!

Frink: ... but suppose we extend the square beyond the two dimensions of our universe, along the hypothetical z-axis, there.

Everyone: [gasps]

Frink: This forms a three-dimensional object known as a "cube," or a "Frinkahedron" in honor of its discoverer, n'hey, n'hey.

Homer's voice: Help me! Are you helping me, or are you going on and on?

Frink: Oh, right. And, of course, within, we find the doomed individual."
