 Red Skelton (qv) had a reputation among comedy writers as being  extremely difficult to work with, since he didnt like writers in  general and resented CBS for insisting that he use them on his show;  he wanted to write all the sketches himself, his reasoning being  that no one knew his characters as well as he did.  Sherwood Schwartz (qv), prior to taking the position as head  writer on the show, had it written into his contract with CBS that  Skelton was under no circumstances allowed to discuss anything about  a shows script with him before he was given it prior to taping,  which often resulted in Skelton not knowing what a sketch was about  or even what character he would be playing until shortly before  airtime. Thats why Skelton would often break character in the  middle of a skit and turn to the audience and say something like,  "Dont blame me, folks, I dont write this stuff."
