A man wondered if having sex on the Sabbath is a sin. The reason is because he is not sure if sex is work or play. So he goes to a priest. He asks for the priest's opinion.

After consulting the Bible, the priest says, "My son, after an exhaustive search, I am positive that sex is work and is therefore not permitted on the Sabbath."

The man thinks, "What does a priest know about sex?" So, he decides to ask a minister.

The minister gives the same reply as the priest had given him. Sex is work, and therefore not permitted on the Sabbath.

Not pleased with the reply, he seeks out a Rabbi. The Rabbi ponders the question, then states, "My son, sex is definitely play."

The man asks, "Rabbi, how can you be so sure when so many others are convinced that sex is work?"

The Rabbi replies, "If sex were work, my wife would have the maid do it."
