The Moose hunters
Two guys in Canada go hunting Moose, they have a Moose skin they had from a previous hunt and a Moose call device.
Deep in the wilderness they climb into the skin and are kneeling in the long grass, the guy in front is blowing the decoy when he suddenly hears the thunder of hooves, he looks behind and sees this enormous Moose galloping towards them, his mate says "what we gonna do now ?", the guy in front says "I'm gonna start eating grass I advise you to brace yourself".
