Zim: Why did this happen, GIR? I just upgraded your guidance chip!
GIR: Oh. I left that at home.
Zim: Left what at home?

Zim: Why, GIR?
GIR: To make room for the cupcake!

I'm hoping that these will get better as I go along, but feel free to add more, as I will probably run out before i get to #1.
