Sometimes comedy magazines publish rude pieces about Vegas cat-training magicians. Then sometimes those magicians get mauled viciously by their cats and you pull the piece from your comedy magazine. However, Google cares enough to preserve everything for us. Check out the Onion's deleted take on Roy: "I think I've added a great deal to the show. Without me, Siegfried would just be some magician with a bunch of dancing girls, laser lights, and fog machines. I was the one who added the cats, starting with our beloved Chico."
