1. Seven – MARRIED WITH CHILDREN
The worst of the lot even though he lasted on his show for the least amount of time. In Season 7 of MARRIED WITH CHILDREN, Peggy’s redneck cousins came for a visit and left their bratty son Seven behind when they left. Oh God, Seven was dreadful. The child actor was possibly the worst kid actor I have ever seen, he always seemed to be looking off to the side like he was being fed his lines by his mom or something. Luckily the producers of the show realized the disaster they were in the middle of creating and unceremoniously dropped the character from the show. In later episodes they would even make fun of themselves by having characters make mention of Seven’s disappearance or use the character in sight gags like having his picture appear on the back of a carton of milk.
