Farnsworth: Good news, everyone! I've invented a device that allows you to operate equipment from great distances. I call it "the fing-longer". Observe. (He aims the fing-longer at a button on a tv screen) And, here we go. (The TV screen, turns on) There!
Fry: Ooh!
Amy: Wow!
Zoidberg: Ah!
Farnsworth: Pretty long, eh?
Fry: Yeah, it's really long. But what did you just turn on with it?
Farnsworth: Oh, that's just the What-If machine I invented. You pose it a What-If question and it generates a video simulation of what would happen.
Fry: Does it really work?
Farnsworth: Of course it works! It's just not very long...
