Duck Dynasty on College GameDay: Willie Robertson Sings Katy Perry, Lee Corso Picks LSU

College GameDay was it’s usual entertaining mess as Duck Dynasty’s Willie Robertson and Jace Robertson appeared as celebrity guest pickers. Everyone held tiny Marucci bats, Willie Robertson sang Katy Perry and Lee Corso wore a giant fake beard. Plus there was a duck assassin hiding behind the stage. And when Corso took off his beard, his mic fell off and Kirk Herbstreit had to hold a mic for him.
