A british man, an american and an irish man are all down at the pub. The british man orders another pint, and to his dismay there is a fly in it. He looks at the beer and just pushes it to the side. In a few minutes the american orders another pint and there is a fly in his as well. He shouts at the bartender but eventually just pulls the fly out and drinks the beer. Finally the Irish man orders another pint, and again, there is a fly in it.
Well, his face starts to turn bright red and he gets this crazy look in his eye. He can't say anything for a minute or 2 but finally he grabs the fly by it's wings, throws it on the bar and begins yelling "Spit evry friggin drop back you bastard!!"
