here is a good joke
Three couples wanted to join the baptist church, and old couple, a middle age couple, and a newly wed couple. The priest said they had to abstain from sex for a 2 weeks before they could join the church.
After 2 weeks, the couples came back. the priest first asked the old couple if they abstained from sex. "Not a problem", they said.
Then he asked the middle aged couple. "The 1st week was ok. The 2nd week was hard, but we made it."
Lastly, he asked the newly wed couple. "No, we did not abstain from sex. When my wife bent down to pick up a light bulb, i couldnt help myself, and we had sex right there on the floor".
"Im sorry", said the priest."You are not welcome to the church".
"Thats ok", said the couple, "were not allowed at the grocery store either".
