Joke: Butt Cheek-Fool joke

A young lady got into a terrible car accident. Her face was burned terribly. The doctors couldn't use any skin on her body to graft onto her face for reconstructive surgery. As a result, her husband offered the skin off his butt for the surgery. She had the surgery and was as beautiful after as she was before the surgery. 

One night she and her husband were watching TV when she broke down crying. "What's the matter?" her husband asked. 

She said "I can't believe you did this for me." 

Her husband hugged her and replied, "Don't worry about it, I love you, and I'd do anything for you." 

But how will I ever repay you?" she asked. 

With which he replied, "You don't need to repay me, you wouldn't believe the satisfaction I get every time I see your mom kiss you on the cheek."
