Morris, an 82 year-old man

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."
