A Priest was going on holiday and a young trainee priest was taking over his duties.
Okay, any questions said the Priest to the trainee.
Well Father, said the trainee, I'm a bit worried about how many Hail Marys I should give to people during the confession.
So the Father gave the trainee a list with all the sins and relevant Hail Marys on it.
During the first confession a man came in and said 'Forgive me Father for I have sinned'.
What have you done the trainee asked.
I've had oral sex said the man.
The trainee looked down the Father's list, but there was no mention of oral sex.
Then the trainee spotted a choir boy walking past and said 'pstt, what does the Father give for oral sex'
The choir boy replied 'a packet of crisps and a can of coke'.
