An elderly gentleman went to the doctor for a physical.  A few days later the doctor saw the man walking down the street with a gorgeous young woman on his arm.

A couple days later the doctor spoke to the man and said, “You’re really doing great, aren’t you?”

The man replied, “Just doing what you said, Doc…’Get a hot mamma and be cheerful.’

The doctor said, “That’s not what I said.  I said, ‘You’ve got a heart murmur. Be careful.’
