I may have brought this up once before, but in the early seasons of SCTV remember how, when they did a celebrity impersonation, they would subtly alter the spelling of the name? Like Tom Bosley became "Tom Boslee," or Orson Welles became "Orson Wells?" I've often wondered whether they did this just to be funny, or if they were genuinely concerned about some legal problems? (I know that, in the U.S., there would be no problem as celebrities are public figures considered to be fair game for parody, but as they were producing the shows in Canada, maybe their laws regarding parody are different?)
