A married couple was in a terrible accident where d man's face was severely burned. The doctor said that they couldn't graft any skin from his body as he was too skinny. So his wife decided to donate some of her own skin as her tissue was a perfect match.
However the only skin on her body that was suitable was on her buttocks! So the couple decided that they would not tell anybody abt this and also asked the doctor to keep it a secret.
After the surgery everybody was astounded at the man's new face. He looked more handsome than ever before and his friends and relatives went on and on about his good looks.
One day, when he was alone with his wife, emotion overcame him for his wife's sacrifice and so he said "Dear, I just want to thank u 4 everything u did for me. How can I possibly repay u?"
"My darling", she replied, "I get all the thanks I need every time I see your mother kiss u on the cheek!"
