I was signing the receipt for my credit card purchase when the clerk
noticed that I had never signed my name on the back of the credit card. She informed me that she could not complete the transaction unless the card was signed. When I asked why, she explained that it was necessary to compare the signature
on the credit card with the signature I just signed on the receipt. So I signed the credit card in front of her.
She carefully compared that signature to the one I signed on the receipt. As luck would have it, they matched.
Yo Momma is so fat, when she told me her weight, I thought it was her credit card number!
