A Rabbit goes into a Butchers shop and ask's for a lettuce
The Butcher Say's, we don't have lettuce this is a butcher's shop not a Greengrocer's, try somewhere else
A few day's later the Rabbit walks into the shop again and ask's for a lettuce
The Butcher said, I've told you before, this is a butcher's not a Greengrocer's, now go away and if you come back I will nail your ear's to that chopping block
A week later the Rabbit again enters the shop and say's to the Butcher, A bag of nails please
The Butcher said, We don't have nails
The Rabbit said, I'll have a lettuce then.
