Best and worst character replacements on TV shows

I agree w/ UCL that Coy and Vance sucked d***.

While I enjoyed Frank Burns in M*A*S*H, I think Charles Emerson Winchester III was an upgrade for the show.

What are some of the best and worst switches in sitcoms, movies, game shows etc. through the years?

wasn't that little **** "Froggy" a replacement on The Little Rascals?

W__T__F was up with that kid????
