Doctor's Orders

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, the doctor met him again, and said, "You're really doing great, aren't you? That was quite the gorgeous young lady I saw you with!"

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."
