Shipwrecked, One Man And A Dozen Women
The group consisted of 12 women and 1 man. After a few months, the women grew horny and it was decided that the man needed to take two women a day and they allowed him to have Sundays off.
One day on a day off, he was just relaxing when he noticed a boat nearing. He felt hopeful that maybe they would be rescued, at last.
The boat was almost to the island when the guy noticed it was a man in the boat. As he got out the first guy said : "Oh my God buddy, am I ever glad to see YOU..."
To which the second guy responded "Well alright sweetie! It's been a long time for me too."
The first man exclaimed "Oh hell, there go my Sundays!"
