Dobbsey and McMoosington are talking.
Dobbsey: Hey McMoosington, I had this question about glaciers and I thought I'd ask you since you're a professor of geology.
McMoosington: I am?
Dobbsey: Yes.
McMoosington: Wow.
Dobbsey: Anyway, I was wondering why glaciers move.
McMoosington: Hmm. I seem to recall it goes something like this...
Cut to a scene of two large blocky glaciers wearing baseball caps. A baseball bat is lying on the ground next to one, and mountains are in the distance.
Glacier #1: Aw man! The ball went all the way into the next valley!
Glacier #2: Hey, you were the one holding the bat. You go get it.
