These two hunters went moose hunting every year without success. Finally
they came up with a foolproof plan. The 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, the 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 bulls' pounding hoofbeats got closer the guy in front said, "OK,
lets 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, "I'm going to start nibbling grass, you better
brace yourself".
