ESPN's "College Gameday" is in Louisville in advance of Saturday night's prime-time matchup between the Cardinals and Clemson. As you might expect, the fans in attendance brought plenty of creative signs to taunt the Tigers. One sign made fun of Lamar Jackson beating out former Clemson quarterback Deshaun Watson in the 2016 Heisman Trophy voting (and Clemson's love for Howard's Rock in Death Valley) with this Halloween-themed Charlie Brown sign. 

Watson saw it and responded by flashing a photo from his own trophy acquisition history, celebrating the College Football Playoff National Championship win against Alabama in January.
