"Nurses aren't supposed to laugh." Bob 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," Bob 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," Bob replied. Things went downhill from there.
