Do you always drink in that position?
Speaking of drinking and tattoos; a friend of mine back in the Marines had a tattoo of a rooster on a hangman's noose below his kneecap. He would be in a bar (often) and bet fellow drinkers that he had a cock that hung below his knees. Well of course they wouldn't believe him so he would prove it. That tattoo generated some serious drinking money.
Unfortunately, my friend ended up on dialisys due to kidney failure. The cock has retired.
There's a moral to this story somewhere....
