One of my favorite comics to color recently was Casper the friendly ghost! I wouldn't have expected it to be so fun, but it was done by the famous who took time out of her busy schedule working on my little pony, to work on this great comic for 3 issues! So obviously:
Casper! Wow, that's one ghost that just won't die. I suspect that as long as there are corpoate lawyers to defend copyrights, characters like Mickey Mouse, Scooby-Doo, Richie Rich and Spiderman will never perish. Long after we've forgotten who Abraham Lincoln, Winston Churchill and Caligula are, we'll still have to drink milk shakes from a paper cup with Casper the Friendly Ghost printed on the side.
