Video Wars: Motorcycle Mayhem!

Mark's pick takes us to an indoor fundraiser -- where a biker got overly excited and popped a wheelie -- right into a wall! Dayna's vid has a hop-happy dude attempting to leapfrog an oncoming motorcycle -- but his helmet isn't shielding him where he needs it most!

Tell "Extra" -- which motorcycle video revved up your laugh reflex?
