A bartender is closing for the night when there's a knock at the back door.
When he answers, a dirty-looking homeless guy asks him for a toothpick.
The bartender is a little surprised, but he gives him a toothpick and the guy walks away. A few minutes later, there's a second knock at the door.
When he answers, there's another homeless guy outside who also asks for a tooth pick.
The second man gets his toothpick and off he goes.
A few minute's later, there's a third knock a the door and a third homeless guy is standing there.
"Let me guess," the bartender says. "You want a toothpick." "
Actually, no, but can I have a straw?" the homeless guy replies.
The bartender gives it to him and says, "Two guys wanted a toothpick and you wanted a straw. What the hell is going on?"
"Well some drunk girl threw up outside but all the good stuff's gone already."
