Jon: Garfield, why don't you catch mice?
Jon: Are you afraid of them?
Jon: What power do they have over you?
Garfield: Tiny little incriminating photographs.

This comic has been produced by applying the identity function simultaneously to every pixel of the comic of 2002-09-05.
I don't think it's funny by itself*, but it might by funny after the sum, average, division, and polar coordinate transform "functions" on Garfield.
* ED: Ouch!
