Married With Children

The Oliver Factor: Seven
Played by: Shane Sweet
Television shows often run the risk of ruin when adding a kid.  Married with Children did just this when they added Seven to the cast. 

The kid arrived September 13, 1992, in the seventh season when Peggy's cousin leaves them the child.  This would prove to be the demise of the show. 

The Bundy's were known for negelecting their children and now we see Peggy caring for this kid?!?  It goes against what this show was all about.

Shane Sweet played Seven.  Married with Children was his major success, although he has appeared in many TV movies.

Last we heard of him was some very forgettable TV projects.
