So there's this great, dirty anecdote about Samuel Johnson. He wanders into a room looking perhaps more unkempt than usual with his breeches unbuttoned and an uptight lady squeals something along the lines of "Sir, your penis is sticking out!"
To which Dr. Johnson replies, "You flatter yourself, Madam . . . it is hanging out."
Such a useful anecdote. But I wish there were a girl version of this.
