[The Deuce]

Go to the doctor ASAP. There is a guy down here who is a shoulder specialist. I need to call him about mine. Messed it up in a motorcycle accident about two years ago. Pops like when you crack a knuckle. My Dr, said that I was too young to have a problem like that. Since you're younger than me, it should be fixable whatever it is.

For those of you keeping score at home, I don't know of any joints other than in my skull that I cannot crack.
