A guy walks into a doctor's office and stutters, "Da-da-doc, I've ba-ba-been sta-sta-stuttering for ye-ye-years, and I ca-ca-can't stand it anymo-mo-more! Can you he-he-help me?"
The doctor answers "Well, I'll have to give you a thorough examination first, but in some cases there is a cure." So the doctor puts the guy through a battery of tests, and says, "I think I know what's causing your stuttering."
The guy excitedly asks, "Well, wa-wa-what is it, da- da-doctor?"
"It's your penis. I know that sounds crazy, but you have an unusually large penis - it's almost two feet long. It seems the weight is putting a strain on your vocal cords which most men never have to deal with."
The guy asks, "Wa-wa-what can we da-da-do?"
"Well, we could remove it and transplant a shorter one."
"Do it!" the guy replies. So they go through the operation, and three weeks later the guy comes in for a follow up appointment.
He says, "Doc, you solved my stuttering problem. I don't know how to thank you. But I've only had sex once in three weeks - my wife just doesn't like it anymore with my new, shorter penis. I've thought about it, and I decided I can put up with the stuttering easier than going without the sex - I want you to put my long one back on."
The doctor says, "No-no-nope. A da-da-deal's a da-da- deal!"
