I don't even want to go into that blight of the sitcom world, Joey Lawrence. Bad, bad, bad. I'm collecting for Jerry's Kids. I did not see that horrible episode on your list when Andy Gibb was on. It totally jumped the shark when Matthew became a regular.
Desperation is an understatement.
Not one but two supposedly cute kids to save Nell Carter's career. Nell Carter's character was named Nell. Joey Lawrence's was named Joey. Matthew Lawrences was named Matthew. Learn to play a character other than yourself.
