A man had a bad case of stuttering. He went to many doctors over the years, but none of them could help him. Finally one doctor said to him "I believe I found the reason for your stuttering".
The man asked, "Wha.. wha.. wha..what is my pro.. pro.. problem."

The doctor replied, "Your ***** is very, very large. The weight of your ***** is causing a strain on your larynx, and this results in your stuttering. The only solution to this is to perform a ***** transplant." The man was really tired of his stuttering, so he agreed to a transplant. Several days later the doctor called the man up and informed him that they have found a suitable donor. The transplant operation was successfully performed and the man could speak without any stutter.

At first he was happy, but after a while he began to miss his large *****, and how the girls used to love it. He finally went back to his doctor and said, "Doctor, I am grateful for the opportunity you have given me to speak without a stutter, but I miss my old *****. Please find the transplant donor and tell him that we have to exchange penises back."

The doctor shook his head and replied, "That's im.. im.. im.. impo.. impossible."
