A byte walks into a bar and orders a pint. Bartender looks at him and asks him what's wrong. Byte says, "Parity error." Bartender nods sympathetically and says, "Yeah, I thought you looked a bit off."

It had me laughing for a while.

Two neutrons are walking down the street and one says "I just lost an electron."

"Are you sure?"

"Yes, I'm positive."
