"America's Funniest Home Videos" begins its 21th season with all-new footage of what happens when adults, children and animals are at their spontaneous best. Video highlights of this season's opener include a bulldog drooling excessively in the car over a man's sandwich, getting slobber everywhere; a music montage featuring men getting waxed; a man showing off his new motorcycle and immediately crashing into a curb; and siblings arguing over the merits of "AFHV" host Tom Bergeron vs. former host Bob Saget.
