A man goes to the doctor because

A man goes to the doctor because his penis has turned a greenish color.

The doctor takes a look and says “I’m really sorry but it looks like you have a rare case of Hong Kong dong. I’m afraid the only option is to amputate”

The man is in disbelief and goes to get a second opinion.

“Yup unfortunately you have got Hong Kong dong. It has to be removed”

In desperation the man books a flight to Hong Kong and finds an English speaking doctor and explains his case.

“Oh those silly american doctors always so quick to chop. There is no need it’s going to fall off by itself soon”
