A guy goes in to his doctor's office and says, "Doc, you gotta help me. I got 14 kids and I don't want anymore".
The doctor gives the guy a pack of condoms and says, "Before you have sex, put these on your organ".
9 months later the guy goes back to the doctor and says, "Hey doc, the condoms did not work. My wife just had another baby"!
The doctor asks, "Did you put the condom on your organ like I told you to do"? And the guy says, I don't have an organ so I put them on my piano instead".
