Two Toothpicks and a Straw

One night as a bartender is closing up his bar, he hears a knock at the back door. When he opens the door, there stands a bum who asks, "Can I have a toothpick?"

The bartender gives him a toothpick and continues cleaning up his bar.

Five minutes later, he hears another knock at the door. Again, there stands another bum who asks, "Can I have a toothpick?"

The bartender gives him a toothpick and continues cleaning up the bar.

Five minutes later, he hears another knock at the back door. This time, there's a bum asking for a straw. The owner gives him a straw, but finally asks what's going on out there.

The bum replies, "Some lady threw up in the back, but all the good stuff is gone."
