Looks like things aren't looking good for some former 'Happy Days' cast members. Anson Williams, Don Most, Marion Ross, Erin Moran and the estate of Tom Bosley are suing CBS. They say they haven't been paid for merchandising and were supposed to be paid 5% from the net proceeds. Maybe Ron Howard can cast them all in a movie together if CBS fails to pay up. Watch what the cast has to say after the jump.
