TSA: Turn on your laptop.
Fellow: Can't. It's broken.
TSA: Why would you fly with a broken laptop?
Fellow: My brother fixes them. Told me to bring it along.
TSA: And what's that attached to it?
Fellow: Cooling fan.
TSA: No such thing.
Fellow: Dude. This is one right here. It's see-through. You can see the blades.
Fellow: Fan blades.
TSA: I'm afraid I'm going to have to break these things with a hammer.
TSA: Don't worry. I'll give you a receipt.
Fellow: But why? If you seriously think there might be a bomb in there, how is hitting it with a hammer making anyone safer?
TSA: Hey, Jim? Can you tase this guy? He said bomb.
