A Liverpudlian man, A Brummie man and a Cavan man walk into a pub and they all order a pint of Heineken, as they are served a blue arsed fly lands in each of their pints
The Liverpudlian man immediately pushes his pint away in disgust, The Brummie man thinks to himself and he too eventually pushes it away also but the Cavan man quickly grabs the Fly by the back of the neck and shouts, that's mine, spit it out you little basterd, spit it all out
