From 1998 to 2001, CN's promo department skewered modern sports telecasts- and especially the Super Bowl- by broadcasting The Big Game; each year featured a bunch of shorts with classic rivalries edited together to seem like a football game. And each year, it ramped up in absurdness and parodies. 1998, with Tom vs. Jerry, was fairly simple. But the 1999 matchup, Sylvester vs. Tweety, really took things to a new level- corporate cousin HBO loaned out the crew at the time from Inside the NFL to make a fake pregame show; also added to the mix were fake commercials and an Acme Corporation-sponsored halftime show. 2000 took it even further- in addition to fake commercials for the Robotic Way, Wayne Enterprises and Spinach, and a bungled Spacely Sprockets halftime show (we ended up seeing Fred and Moltar manning master control for 10 minutes, but the pregame show was now backed by the Slate Rock and Quarry Co., and John Madden and Pat Summerall were the main commentators, with Bubba Smith and Scott Hamilton as the sideline guys at Chuck Jones Stadium. Not only that, but the scripts were peppered with parental bonuses galore (ie. referencing how they had started telecasting "Desert Division" games back in October of 1999- when CN finally nabbed the rights to the Wile E/RR Toons from Nickelodeon). Not only that, but the late great Harry Kalas voiced a recap of the previous Big Game, and even a "Look Back" special on the other Big Games was produced. 2001 and Bugs vs. Daffy saw the return of the Inside the NFL crew, plus Harry Kalas; supplementing it was a tailgate party on Cartoon Cartoon Fridays. Unfortunately, it came to and end after that, but the CN promo dept. did their absolute best to parody everything people take for granted in sports coverage and the Super Bowl, and yet make it so serious.
