In both movies there's a gag with an object on a railroad track. You see a train coming, you think the train is going to crash into the object, but the train just passes the object. Now you think all is safe, but at that time another train comes from the opposite direction and crashes into the object.
In both movies there's a gag with the lead role player sitting on a moving vehicle. The driver falls off this vehicle, but the lead role player doesn't notice this and the vehicle keeps moving.
