Some friends and I have been self-inducted members of the Turtle Club ever since we read about it in, I believe, Breakfast of Champions.

We kind of used it as a game (similar to the penis game) where we'd ask each other if they were a member at completely inappropriate times and force them to answer multiple times until we were satisfied that it was loud enough that they had sufficiently embarrassed themselves or at least caused a scene.

I'm not sure why, but it's upsetting, that in order to be official, I have to pay $5. At least it's for a good cause.
