During WWII, group of American pilots founded The International Association of Turtles in an English pub. The basic rules for membership:"You must think with a clean mind and you must be willing to stick your neck out for yourself and for other people in need."
The Silent Porn Star blog came across an early membership card, the back of which reads (typos and all):
We assume all prospective Turtles own a Jack Ass. On this assumption is the reason for the password.
This password must be given if you are ever asked by a fellow member, "Are you a Turtle?" You MUST then reply "You bet your sweet ass I am." If you do not give the password in full because of embarassment or some other reason, you forfeit a beverage of his choice. So always remember the password.
As all members are of clean mind to become an official Turtle the person must solve the following riddles with clean-minded correct answers:
1. What is it a man can do standing up, a woman sitting down, and a dog on three legs? (Answer: shake hands).
2. What is it that a cow has four of and woman has only two of? (Answer: legs).
3. What is a four letter word ending in 'k' that means the same as intercourse? (Answer: talk).
4. What is it on a man that is round, hard, and sticks so far out of his pajamas that you can hand a hat on it? (Answer: his head).
You are now a member of The Turtle Club. Govern yourself accordingly and produce new members.
