Three Hells Angels
 

Three Hells Angels are sitting at a table in a transport cafe when in walks a Nun, takes a seat next to them and begins to eat.
Astonished, one of them says, "I went to my parents wedding last week and we all got rat-arsed."
Being quick on the uptake the second one says, " My dad says he will marry my mum next year."
Despite this the Nun stays right where she is.
In desperation the third one says, " My old man will never ever marry my mum."
The Nun looks up from her food and says, " Would one of you bastards please pass the salt."
