Weirdos from Another Planet by Bill Watterson

Another Calvin and Hobbes gem. Again, in black and white, though. Below (rough) excerpt suffices to an extent:

Calvin to Susie: "Can I borrow your black crayon?"
Susie: "Ok, but dont break it and dont peel off the side paper. Also draw on all sides so that the end remains pointy."
Calvin: "Geez, why dont you get an insurance on it!"

The Revenge of the Baby-Sat by Bill Watterson

Another Calvin and Hobbes gem! The episode of Susie Derkins being sent to Principal's office because of Calvin's pranks is hilarious. Would have been better if print was in color.
