[In echo voice] Hello? Can anybody hear me?
Uh... I'm somewhere where I don't know where I am!
Do you see towels? If you see towels, you're probably in the linen closet again.
Just a second! ... No, it's a place I've never been before!
Heh, the shower! [Patty and Selma laugh]
Homer, this is your physician, Dr. Julius Hibbert. Can you tell us what it's like in there?
Um, it's like, uh... did anyone see the movie Tron?
Yes. I no. I mean, no. No.
[Frink draws a strange diagram on the wall]
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... [lights off] the third di-mension.
[switches the light on] Sorry.
[draws a square on the chalkboard] Here is an ordinary square.
Whoa, whoa! Slow down, egghead.
But suppose we extend the square beyond the two dimensions of our universe... along the hypothetical "Z" axis there.
This forms a three-dimensional object known as a cube, or a "Frinkahedron," in honor of its discoverer, n-gl'hey, n'hey.
[in echo voice] Help me! Are you helping me? Or are you going on and on?
Oh, right. And, of course, within we find the doomed individual.
Enough of your borax, Poindexter! A man's life is at stake. We need action!
[Wiggum takes out his gun and fires into the wall]
Take that, you lousy dimension!
[in echo's voice, disembodied] Help! I don't have much time.
That does it! I'm going in!
[Bart runs into the dimension, but Marge catches him and fails. He keeps running until he turns 3D too and looks around]
[the camera rotates and zooms out into a bird's-eye view of the green grid, Homer is nearing the edge of the green grid]
Oh, my God! I'm gonna be sucked into a black hole! I'm gonna be sucked into oblivion! And what's gonna become of me of the other side? I don't know!
[Bart climbs onto the XYZ street sign]
I can't get any closer. You'll have to jump!
[runs into a hole, breaks into pieces]
Crap, crap, crap, crap, crap, crap, crap, crap, crap, crap, crap, crap--
[the world exploses as Bart gets pulled back]
Well, we hit a little snag when the universe sort of collapsed on itself. But dad seemed cautiously optimistic!
[in echo's voice] Craaaap!
Be strong, Marge. I'm sure he's gone to a better place.
