A group of people were in a shipwreck and were stranded on an island.
The group consisted of 12 women and one man. After a few months, the women became horny and it was decided that the man needed to take two women a day, but they allowed him to have Sundays off.
One Sunday, the man was just relaxing when he noticed a boat nearing. He felt hopeful that maybe they would be rescued, at last.
The boat was almost at the island, when the guy noticed there was a man in the boat. As he got out, the stranded guy said, "Oh my God, buddy, am I ever glad to see you," to which the second guy responded, "Well all right sweetie! It's been a long time for me too."
The first man exclaimed, "Oh hell, there go my Sundays!"
