walk into a bar. the man says, "i'll bet $500 that i can put my privates into this turtles mouth no harm will come to me". the people in the bar take up a collection to match the $500 and take the bet. the man takes out a little ball peen hammer and hits the turtle on the head. the turtle opens wide and the man places his privates in the turtle's mouth. it's mouth closes and in a few minutes it opens again and the man's privates are unscathed. the man collects his money. then he says "now i'll bet $1000 that nobody else will try this". the bar is totally silent for a minute or two, and then from the back of the room a blonde woman says " i'll try it but i don't want you to hit me on the head with that hammer"
