In episode four of On This Very Screen, the gang takes on the gargantuan mixed-martial arts comedy, Knucklehead, starring the "Big Show," Paul Wight and Mark Feuerstein from USA's "Royal Pains." Touted as WWE Studios' first comedy, Knucklehead combines the plot of "Nacho Libre" with enough fart jokes to power the city of Los Angeles, and the results are goddamn glorious. How do bears get fighting licenses? Since when did orphans have to audition to be adopted? And what in the blue hell is an "interesting Jew?" All these questions and more are addressed in our funniest episode, yet!
