Det här är 2005-filmfilen " Larva ".
Den ko-tippningsplatsen beskrivs här ;
The movie starts off in a Missouri field with four teenagers going cow tipping. The cow in question is already dead on its feet, obviously the victim of the title beasties. (Ah, the irony!) However, the scene ends flat with the teens running off prior to the larva sluggishly (no pun intended) breaking through the animal's hide as the credits begin.
Den ko-tipping scenen kan ses rätt i början av filmen. Tyvärr är klippet på hindi, men du får idén.
