A guy walks into a bar and
orders a beer. He only brought enough money for one beer though.
As he’s drinking his beer, which was quite expensive, he realizes how
bad he has to go to the bathroom. Not wanting anyone to drink his
expensive beer, he takes out a 3×5 note card and writes on it, „I
SPIT IN
THIS BEER“, and walks to the bathroom.
When he comes
back about 15 minutes later, there’s another 3×5 note
card next to
his beer saying, „I SPIT IN IT TOO“.
