9x21 - The Jeffersons

A young boy befriends Louise and Helen and they become convinced that he has a crush on one of them but the real reason he befriended them was to get to George. He wants to ask George if he would participate in a father-son bowling tournament, since his father is supposedly dead. However, the boy does indeed have a father who's alive, but not-so well, he's a parapalegic.
