Two men walk into a bar, the first man is tall, loud and talkative. The other man is short, quiet and funny looking.
The first man says to the second, “donkey get us a pint in lad, I’m going for a slash.”
The second man walks to the bar and orders two pints. The barman is observing the men and over the next week he notices that the tall man refers to the short man as donkey.
A couple of weeks pass and finally the mystery gets the better of the barman and he asks the short man, “Why does he call you donkey then?”
The short man looks up and says “Oh heehaw heehaw heehawlways calls me that.”
