Continuity mistake: After Steve accidentally jabs the wood burner into Stan's penis, he screams and a avalanche occurs. Then when Stan screams a second time due to putting the cream on his penis, the avalanche happens again but the same amount of snow is on the mountain even after a load already fell off it.
