A guy goes to the doctor.
"Doc, I can't stop singing 'The green, green grass of home.'"
"That sounds like Tom Jones syndrome."
"Is it common?"
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 dick the doctor had ever seen. It wasn't any bigger than a AAA battery.
The doctor burst into uncontrolable 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?"
Morris, an 82 year-old man, went to the doctor to get a physical.
A few days later, the doctor saw Morris walking down the street with a gorgeous young woman on his arm.
A couple of days later, the doctor spoke to Morris and said: "You're really doing great, aren't you?"
Morris replied: "Just doing what you said, Doc. Get a hot mamma and be cheerful."
The doctor said: "I didn't say that. I said, You've got a heart murmur – be careful."
