A man comes to the doctor and says, "m-m-m-my d-d-dick is so pressurized that I st-st-stutter."

The doctor tells him he will give him a dick transplant. He loses his 3-foot-long dick for a 4-inch-long dick.

He comes back in a week and says, "Now my wife wont have sex with me. May I have the old one back?"

The doctor replies... "A d-d-d-deal's a d-d-d-deal."
