Comedy Central's decision to replace a Wednesday repeat of the Scientology- and Tom Cruise-prodding South Park episode with a Chef's Chocolate Salty Balls encore has fueled talk that Cruise threatened not to promote Viacom-owned Paramount's Mission: Impossible III if the switch was not made. A rep for Cruise denies the strong-arming and the semiofficial "spin" is that the Chef-centric substitute was chosen as a tribute to Isaac Hayes, who recently quit the series... due to its Scientology riff. But South Park creators Trey Parker and Matt Stone still cry foul, saying in a statement to Variety, "Scientology, you may have won this battle, but the million-year war for Earth has just begun!... You have obstructed us for now, but your feeble bid to save humanity will fail!" You gotta love those guys.
