An old wino staggers into a bar and the barman orders him to get out.
He agrees but only if he can have a cocktail stick.
The barman gladly hands him a cocktail stick and the wino staggers back outside.
A few minutes later a second wino staggers in and demands a cocktail stick, staggering back outside with his cocktail stick in his hand.
When a third wino comes in, the barman has another cocktail stick ready but the wino refuses it asking for a straw instead.
When the barman asked why he needed a straw instead of a cocktail stick, the wino says that someone had been sick outside but all the chunky bits have gone.
