Some of my favorite nerdy jokes:
A neutron walked into a bar and asked, "How much for a drink?" The bartender replied, "For you, no charge."
Man, entropy isn't what it used to be.
A Helium atom walks into a bar and the bartender asks: "Why the long face?"
Helium doesn't react.
A byte walks into a bar and orders a pint. Bartender asks him "What's wrong?" Byte says "Parity error." Bartender nods and says "Yeah, I thought you looked a bit off."
A physicist, an engineer, and a statistician were out game hunting. The engineer spied a bear in the distance, so they got a little closer. "Let me take the first shot!" said the engineer, who missed the bear by three feet to the left. "You're incompetent! Let me try" insisted the physicist, who then proceeded to miss by three feet to the right. "Ooh, we got him!!" said the statistician.
