"Nurses aren't supposed to laugh." Frank declared.

"Of course I won't laugh, I'm a professional
nurse. In over twenty years I've never laughed at a
patient."

"Okay then," Frank said and proceeded to drop his
trousers, revealing the tiniest man thingy the nurse had
ever seen. Length and width, it couldn't have been
bigger than a AAA battery.

Unable to control herself, the nurse started giggling then
almost fell to the floor laughing. A few minutes later
she was able to regain her composure.

"I'm so sorry," said the nurse. "I
don't know what came over me.

On my honor as a nurse and a lady, I promise it won't
happen again. Now tell me, what seems to be the
problem?"

"It's swollen," Frank replied.

Things went downhill from there.
