The Big Game XXVII: Sylvester vs. Tweety

The Big Game XXVII: Sylvester vs. Tweety was a 4-hour marathon that aired on Cartoon Network on Saturday, January 30, 1999, from 5:00 PM to 9:00 PM, with the first hour consisting of a pre-game show that featured analysis by experts Jerry Glanville, Nick Buoniconti and Len Dawson (borrowed from sister network HBO's Inside the NFL) as well as narration by Harry Kalas. The marathon featured 18 Looney Tunes shorts starring Sylvester and Tweety as well as play-by-play and color commentary from Pat Summerall and John Madden during commercials. The marathon was also aired the following day (Super Bowl Sunday) from 12:00 PM to 4:00 PM.

This was the second in a series of four Super Bowl spoof marathons that aired annually on Cartoon Network from 1998-2001. These marathons came to be known as "The Big Game"; however, only the final two actually featured this moniker.

The game itself used clips from the Sylvester & Tweety cartoons Bad Ol' Putty Tat (for the first half) and Tweety's S.O.S. (for the second half).
