A bum walks into a bar and asks for a toothpick so the bartender gives him a toothpick. Another bum walks into the same bar and asks for a toothpick to so the bartender gives him a toothpick. A third bum goes into that same bar and asks for a straw so the bartender gives him a straw and asks " Why don't you want a toothpick like all the other bums?"
The bums says " Well.. a guy puked out in the ally and the other bums got all of the good stuff."
