The young man is eating in a restaurant and as the lady leaves he shouts out "good bye mom" and of course then gets stuck with her bill.

It was told to me as if it was a true story though and continued on from there. The young man runs out the door and proceeds to chase down the sidewalk in pursuit of the woman. After all sorts of obstacles are hurdled or side stepped the fellow finally makes a lunging dive and grabs the lady by the foot. She struggles and drags the fellow down the street (the length of the struggle depends on how long you want to milk your audiences attention) as he hangs onto her leg.

The punch line went something like "I pulled and pulled on her leg for what seemed like forever... kind of like I'm pulling on your leg right now".

My sister's baby sitter told me this back in the 1970's (I was in junior high) and she had me by hook, line, and sinker till she closed the deal and told the punch line.
