This old wino staggers into a bar and the barman immediately told him to get out. The tramp said that he would only leave if the barman
gave him a cocktail stick.
The barman, thinking this was a fair exchange, gladly gave the man a cocktail stick and watched him stagger back outside.
A minute later another old wino walked into the bar and got asked to leave by the barman. This drunk also demanded a cocktail stick if
he was to leave quietly. There had been no trouble the first time so, once again, the barman obliged and the old drunk quietly left.
Soon after, a third wino came into the barman and without hesitation the barman offered him a cocktail stick to leave. This time though the drunk turned him down and said he would only leave if the barman gave him a drinking straw.
Curiosity finally got the better of the barman and he asked the old drunk why he wanted a drinking straw when the other two drunks
had asked for cocktail sticks.
The wino said "Well, someone was sick outside and all the lumpy bits have gone now!"

YUK.  Didn't see it coming and am happy its gone.
