Ok, this is one i got a few days ago.

There is a pub that's on the tenth floor of a skyscraper, and there are two men, one drunk, sitting by the window.
"Did you know," says one. "That there's a draught so strong that if you jump out the window, you'll go all the way around the building and back in the window."
"Your having a laugh!" says the other man. so the first guy jumps out the window, and flys all the way around the building and back in the window. the other man says: "Do that again!" so the first guy jumps out the window, flys all the way around the building, and comes back in the window. so the other guys says: "Well, if you can do it, i can!" so he jumps out the window, and falls to the ground, splut! the barmaid come over to the remaining man and says: "Superman, your a bastard when your drunk!"
