Something Always Happened To The Newsman
During the first season, bad things rarely happened to him. After the first season, it was normal for something really bad to happen to him.
Also, the episode where he got eaten by a desk was uncle Deadleys first episode, though he wasn't properly introduced untill a few episodes later, which is when he told kermit to leave or be doomed.
Maybe the band threatening to quit was part of Uncle Deadleys curse. Or Gonzo's long arm, or Gilda radner accidently getting glue all over the theatre, or Statler and waldorf keeping score of the acts (where the muppets kept getting amazingly low scores while the guest got amazingly high scores), or.....
