A man with a stutter goes to the doctor

A man goes to the doctor to consult regarding his stutter.

  Man: "D-d-d-doctor, have the re-re-re-results come back yet about the source of my st-st-st-stutter?"

  Doctor: "Yes, after extensive examination, I have determined that the reason for your stutter is because of your enormous penis. We will have to perform surgery and replace it with a regular sized one."

Conflicted, the man ultimately agrees as his terrible stutter has hindered him since childhood. He undergoes surgery and had his penis replaced. Thankful, he goes back to his home and returns to his life.

After a few days, the man returns to the doctor troubled.

  Man: "Doctor! I would like to have my old penis back again. My stutter is gone but I can no longer satisfy my wife in bed like I used to. Please perform surgery on me again."

  Doctor: "N-n-n-no takebacks!"
