A few years back, a friend of mine who works for NBC at 30 Rock gave me the after-hours tour. When we went to Studio 8H (where Saturday Night Live is shot), the carpenters were still at work for that week's episode. One of the carpenters was really cool and showed us around... so onto the stage, up the stairs and through the door (the one the guest hosts open at the start of the show). The carpenter was pointing out all kinds of little things backstage. Over one threshold, was a sign that read "WATCH YOUR HEAD, FARLEY" Farley was written in ballpoint pen, apparently by the man himself.
