A nun was quietly sitting alone in a train compartment when a young drunken man entered. He was carrying a large bag of prawns and started eating them whilst flicking the shells at her. He cursed her loudly saying "I really hate all religious types - especially Roman Catholic cunts like you." He continued to fire prawn shell missiles at the upset nun.
Suddenly she' had enough, stood up, pulled the sliding window down, grabbed his prawn bag and threw it out of the train. Then she pulled the communication cord. The guy screamed "That'll cost you £100 you stupid woman and you'll be in trouble. She responds "Not half as much as you when the railway police smell your fingers."
