A nun is sitting on a train opposite a skinhead who is eating a bag of prawns.
Everytime he eats one he spits the head at her and she is disgusted and throws it out of the window.
Eventually she gets p*ssed off and pulls the emergency cord.
The skinhead looks at her and says ''You'll get fined £50 for that you stupid tart'' and laughs..
She laughs back and says '' When I cry rape and they smell your fingers. You'll get 10 years you bald b*st*rd!''
