Get a hot mamma

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, "Wow, you're really doing great, aren't you?"

Morris replied, "I'm 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.'"
