I read this one, about dwarven spirit, on the net somewhere a long time ago:
A dwarf comes into a tavern and walks up to the bar. An elf comes up to him and says "I heard you dwarves hold liqour well?" "Aye!" says the dwarf. "Well, I have a wager for you. I'll wager 10 gp that you can't drink 10 pints in a row, without pause. What do you say, will you take the bet?" The dwarf thinks for a little while and says "maybe... hold on a minute" and leaves the tavern. Ten minutes later he comes back and says "I'll take your bet." The barkeep places ten pints on the bar and the dwarf proceeds to down them all, with no pause. "Hmm... looks like I lost the bet" says the elf and pays up, "but tell me, why did you go outside first?" To which the dwarf responds "well, I wasn't sure I could do it, so I had to go to the tavern across the street and try first."
