Bob saw his doctor and asked

Bob saw his doctor and asked if he had ever laughed at a patient.

“In over 20 years I haven’t because I try to remain professional.”

With that Bob dropped his trousers revealing the tiniest weapon the doctor had ever seen.

It wasn’t any bigger than a AAA battery.

The doctor burst into uncontrollable hysteria.

“I’m sorry I really am, I don’t know what came over me, I promise it won’t happen again.

Now what seems to be the problem?”

“It’s swollen” said Bob.
