A 92-year-old man went to the doctor to get a physical. A few days later, the doctor saw the man walking down the street with a gorgeous young lady on his arm.
A couple of days later, when the old man had an appointment with the doctor again, the doc said, "You're really doing great, aren't you?"
The man 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 murmur. Be careful."
