It is Christmas Eve and this chap is on a rooftop about to jump off.
His wife is leaving him for another man, he has lost his job and he owes thousands of dollars to the bank.
Just as he finishes his prayers and closes his eyes, ready to jump, Father Christmas taps him on the shoulder.
"Are you OK?" asks Father Christmas.
The man explains why he is so miserable and gets ready to jump.
"Stop!" shouts Father Christmas. "It's Christmas so I will grant you three wishes to solve your problems on the understanding that you will grant me a small favour in return!"
"Would you?" the man replies. "That would be wonderful!!.....Thank you, thank you!"
Father Christmas promises him that:
"Oh thank you, thank you!" says the man. "What is it that I can do for you?"
Father Christmas asks the man to drop his pants and bend over.
After a quite brutal rogering, which made his eyes water a little, Father Christmas asks the man how old he is.
"36" replies the man.
"Ho Ho Ho, You're a bit old to believe in Father Christmas aren't you?" chuckled the jolly fat gay bastard.
