Three couples walk into a church, an old couple, middle aged and a young couple. They ask if they can join up.
The preist says "Yes you can, if you can go away and not have sex for two weeks,"
Off they all toddle to try and hold it together for a fortnight.
Two weeks later they all come back and the preist asks "So how did it go?"
The old couple reply "Oh yes, no problem at all."
"oh good in you come then," says the preist in a freindly tone.
The middle aged couple come over and the woman tells the priest "Oh, well, um...yes we did manage it but I had to lock him in the shed,"
"Well at least you managed it, in you come," Smiles the preist.
Finally the young couple walk over blushing and the young man explains "I'm sorry father we couldn't manage it..." looking at his wife "you see it was all going well until i saw her bending over into the fridge, i had to have her i couldn't help it,"
The priest frowns and says "Well I'm sorry but you are just not welcome here, goodbye,"
To which the young man replies "Yeah, we're not allowed in Sainsburys again either,"
