S5E36 Bang the Drum Slowly, Dumbass

While wandering through the forest, the boys stumble upon a rhythmic drumbeat and discover Van Driessen with his men's group engaged in their monthly drumming ritual, aiming to release tension as they confront their notions of masculinity. Beavis decides to join in but ends up getting a bit too enthusiastic with the drumming.
