Do you remember Deep Thoughts by Jack Handey from SNL? These are my favourites:
Too bad when I was a kid there wasn't a guy in our class that everybody called the "Cricket Boy", because I would have liked to stand up in class and tell everybody, "You can make fun of the Cricket Boy if you want to, but to me he's just like everybody else." Then everybody would leave the Cricket Boy alone, and I'd invite him over to spend the night at my house, but after about five minutes of that loud chirping I'd have to kick him out. Maybe later we could get up a petition to get the Cricket Family run out of town. Bye, Cricket Boy.
I think a good product would be "Baby Duck Hat". It's a fake baby duck, which you strap on top of your head. Then you go swimming underwater until you find a mommy duck and her babies, and you join them. Then, all of a sudden, you stand up out of the water and roar like Godzilla. Man, those ducks really take off! Also, Baby Duck Hat is good for parties.
At first I thought, if I were Superman, a perfect secret identity would be "Clark Kent, Dentist," because you could save money on tooth X-rays. But then I thought, if a patient said, "How's my back tooth?" and you just looked at it with your X-ray vision and said, "Oh it's okay," then the patient would probably say, "Aren't you going to take an X-ray, stupid?" and you'd say, "Aw fuck you, get outta here," and then he probably wouldn't even pay his bill.
A good way to threaten somebody is to light a stick of dynamite. Then you call the guy and hold the burning fuse up to the phone. "Hear that?" you say. "That's dynamite, baby."
