Lisa: Well, where's my Dad?
Frink: Well, it should be obvious to even the most dim-witted
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: [turning the lights back on] Sorry.
Frink: [drawing on a blackboard] Here is an ordinary square --
Wiggum: Whoa, whoa -- slow down, egghead!
Frink: -- but suppose we exte-end 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: [disembodied] 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.
