I stole these from the New York Times today, but I love them both. You may not "get" the first one if you aren't an electrical engineer, but it's a great joke.

A neutron walks into a bar and orders a beer. “How much?” the neutron asks. “For you” the bartender replies, “no charge.”

Two guys are walking their dogs. One has a big German Shepherd, the other a tiny Chihuahua. They pass by a very fancy restaurant and the guy with the Shepherd suggests they stop in for a drink. “They’re not going to let us in with the dogs,” the man with the Chihuahua says. Just do what I do, his friend assures him. The guy with the Shepherd walks in first and the maitre d’ stops him. “We don’t allow animals in here, sir. Sorry.” This is a seeing-eye dog, the man says. The maitre d’ apologizes and the man with Shepherd sits at the bar. Then the man with Chihuahua comes in.

“We don’t allow pets in here,” says the maitre d’.

“This is a seeing-eye dog,” says the man with the Chihuahua.

“That’s not a seeing-eye dog, that’s a Chihuahua.”

And the man says: “They gave me a Chihuahua?”
