A man was very worried when he went to see a doctor.

"Doctor, I want to let you know that I have a very small penis, and I would like you to not laugh about its size."

The doctor promised and told him that he is very professional.

So the man opened his pants, and there was the smallest penis the doctor has ever seen, it was so tiny that doctor could not help but laugh uncontrollably.

After a while, the doctor apologized and said: "I'm sorry, that was very unprofessional, so what's the problem?"

To which the man replied: "It's swollen."
