I personally don't have any but I'm sure others do.
Not a show in its entirety but the Dream Season of Dallas. I loved the storylines of that year that everyone demanded be changed with main star Patrick Duffy returning. Though I missed Duffy I still say that dream idea was a badbway to introduce Patrick back to the show which erased the storylines of 33 episodes that I thougt were good.
Also I liked Dick Sergeant on Bewiched over Dick York probably because my earliest memories of the show was after York left. When Dick York appeared I was way too young to remember him. So when Bewiched went into syndication my first reaction to Dick York was "Who is this guy?"
