A young man was walking through a supermarket to pick up a few things when he noticed an old lady following him around. Thinking nothing of it, he ignored her and continued on. Finally he went to the checkout line, but she got in front of him. "Pardon me," she said, "I'm sorry if my staring at you has made you feel uncomfortable. It's just that you look just like my son, who just died recently." "I'm very sorry," replied the young man, "is there anything I can do for you?" "Yes," she said, "As I'm leaving, can you say 'Good bye, Mother'? It would make me feel so much better." "Sure," answered the young man.
As the old woman was leaving, he called out, "Goodbye, Mother!" As he stepped up to the checkout counter, he saw that his total was $127.50. "How can that be?" He asked, "I only purchased a few things!" "Your mother said that you would pay for her," said the clerk.
I've heard an ending to that story...it goes like this..

The young man sputtered, "but she's not my mother"
The clerk says "You DID call her your mother didn't you" to which the young man says "umm yes but no but nothing!" before leaving the line and dashing out of the store. He runs out into the parking lot where the lady is just about to pull out. He yanks open the door, shouting at the poor old lady. Everybody in the parking lot started to stare in horror as he starts pulling the lady out of the car. He's pulling her arms...her legs...harder and harder he pull on her leg...just like I'm pulling on yours!
