My friends uncle made a brass trumpet looking thing and the bell points towards your face and what he does is (after some beers of course) tells all the guys that havent seen it that its a univesal game call and it calls everything. I mean everything he says, deer, moose, coyotes, bear everything. Its packed with flour at the bell end and when curiosity gets the best of the drinking man which it usually does they have to hear what it sounds like and when they blow in it, poof, aface full of flour. They got two guys in a row with it one day while the other guy still had flour on his face. When you are not so sober we will say, its hilarious. Give it a shot, Im telling you for a stupid little prank its well worth it.
