A Homeless Man Walks Into a Bar...

... And asks for a toothpick. Without thinking twice about it, the bartender hands the homeless man a toothpick.
About 30 seconds later another homeless mans walks in and asks for a toothpick. Again without hesitation the bar tender hands the homeless man a tooth pick and the homeless man leaves.
Another couple of minutes pass an a third homeless man enters the bar. Confused, the bartender asks,
'You want a tooth pick too?'
To which the homeless man replies,
'No, no. I need a straw. Someone vomited outside, and someone else has already taken the solid parts.'
