An elderly couple toddled into the local McDonalds and ordered one combo meal.
The wife carefully cut the sandwich in two and began to eat her half. The husband respectfully sat and watched.
The eating did not progress quickly, and soon the other customers bagan to notice. Finally one helpful person
offered to buy the couple another meal.
The offer was rejected with the explanation, "We share everything."
Eventually another could stand it no longer and made the same offer. Same rejection: "No thank you, we share
After this had gone on for what seemed to be quite a while, one bystander could no longer stand it and quizzed the man, "Then why aren't you eating? What are you waiting for?"
The reply: "The teeth."
