Number Two!

A drunk looks up from his drink and says, "Bartender, I have to go. Which way is the bathroom?"

The bartender points out the direction, and as the man staggers off, he sez "While you're there, go for me too."

The drunk returns, sits down, then sez "Damn ! I forgot something."

Then, minutes later, returns again and sez, "Hey bartender, you didn't have to go."
