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 lady 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, Doctor, ‘Get a hot mamma and be cheerful.’”
The doctor said, “I didn’t say that. I said you got a heart mummer and be careful.”
