One of the reasons Beverly Hills Ninja is my absolute favorite movie of all times is all the stupid mistakes in it... The dumbest one is towards the end when Chris Farley is lying on top of the big truck inside the warehouse. When the bad guy motions to his ninja folk to get Farley, Farley rolls off of the side of the truck and lands on a conveniently placed airbag the size of a king-sized bed. Easily overlooked, but even more easily spotted...
