These two hunters went moose hunting every year without success. Finally they
came up with a foolproof plan. They got themselves a very authentic cow moose
costume and learned the mating call of a cow moose.
 
The plan was to hide in the costume, lure in the bull, then come out of the
costume and shoot the bull. So, they set themselves up on the edge of a
clearing, in their costume, and began to give the moose love call.
 
Before too long their call was answered by a bull in the forest. They called
again, the bull answered closer to them. They called again, the bull answered,
and came crashing out of the forest and into the clearing.
 
As the bull's pounding hoof beats got closer the guy in front said, "OK, let's
get out and get him."
 
After a moment that seemed like an eternity, the guy in the back shouts, "THE
ZIPPER IS STUCK! WHAT ARE WE GOING TO DO?"

The guy in the front says, "Well, I'm going to start nibbling grass, but you
better fuckin' brace yourself!"
