shake it out

Three guys are sitting at the bar

one is french the other is german and the third is irish

they each order a pint of beer and a fly falls in each of their beers

the french guy puches the beer asides and says he refuses to drink it

the german guy picks the fly out looks at it grunts and flicks it aside and shortly after chugs the beer.

the irish guy picks out the fly squeezes it and yells "SPIT IT OUT SPIT IT OUT!"
