My favourite is the "Peehorn" (from one of those DeerHuntin' Soldier of Fortune type mags). When you're up that tree camouflaged like Rambo, with yer gun at the ready.....and Dadgummit! You just gotta relieve yourself...but the human smell will be a dead giveaway to some Bambi wanderin' into your sights, well just pull out the ol' "Pee Horn", stick yer own horn into it and pee away. 'Course I guess it also works when you're watchin' the big game on the big TV and don't want to miss any commercials.
