Three couples want to join the local church.

Three couples want to join the local church. There is an old age couple, a middle aged couple and a newly-wed couple they all meet with the priest and he says "I would be delighted to have you join this church, but to show you're dedicated to it, you will have to go two weeks without sex to prove yourself."
So they all accept the challenge.

Two weeks later, the couples are waiting in a room to talk with the priest. He calls in the old age couple first, "How did you go?"
So the husband says
"Priest, we're old, we have no sex drive. It was easy for us."

"Alright, you may join my church."
He calls in the middle aged couple next and asks them the same thing.
"Well, it was hard for the first week. But for the second week it was much easier. No sex for two weeks, like we promised."
"Alright, you may join my church."
Lastly, he calls in the newly-wed couple and asks them how did they go?
"Well, it was fine until she dropped the can of paint."

"Can of paint?" the minister exclaims, confused.
"Yeah, can of paint. She bent over to pick it up infront of me. I'm sorry priest, but lust took over me. I had to have her right there and then."
"It's a shame that you couldn't complete your task to join this church. But I am sorry to say, you won't be allowed in this church anymore."
"That's alright" says the husband, "we aren't allowed in the hardware store, either."
