Bill Hutchinson of the New York Daily News is reporting that SYSTEM OF A DOWN got one over on "Saturday Night Live" last night.When the group performed "B.Y.O.B" from their new album "Mezmerize", the show repeatedly muted the F-word in the line, "Where the f--- are you?" But it missed guitarist Daron Malakian's screeched, "F--- yeah!" toward the end of the number. The camera even focused on him as he said it. Fans of the group immediately hailed the move on SYSTEM OF A DOWN's web site, with one noting, "The censors missed at least one 'f--- you.' Which was nice." The band performed a second number, "Aerials", from their "Toxicity" album, without incident. "SNL" traditionally doesn't use a tape delay. NBC did not immediately return a call seeking comment. The show has a history of controversial performances, from Ashlee Simpson getting caught lip-synching to Sinead O'Connor's ripping up a picture of Pope John Paul II.
