A couple of my favorites:
Sometimes when I feel like killing someone, I do a little trick to calm myself down. I'll go over to the person's house and ring the doorbell. When the person comes to the door, I'm gone, but you know what I've left on the porch? A jack-o'-lantern with a knife in the side of its head with a note that says "You." After that, I usually feel a lot better, and no harm done.
One thing kids like is to be tricked. For instance, I was going to take my little nephew to Disneyland, but instead I drove him to an old burned-out warehouse. "Oh, no," I said, "Disneyland burned down." He cried and cried, but I think that deep down, he thought it was a pretty good joke. I started to drive over to the real Disneyland, but it was getting pretty late.
It makes me mad when people say I turned and ran like a scared rabbit. Maybe it was like an angry rabbit, who was running to go fight in another fight, away from the first fight.
