"Moose Hunting" joke

Roscoe and his friend went moose hunting every year without success.

Finally, they came up with what they hoped was a foolproof plan. They acquired a very authentic moose costume and learned the mating call of a cow moose. The plan was to hide in the costume, lure the bull, then jump out of the costume and shoot the bull.

Setting themselves upon the edge of a clearing in their costume, they began to give the moose "call o'love". Before too long their call was answered by a bull moose some distance away. They called again, and the bull answered from somewhere closer. Again they called, and again the bull answered. Soon he came crashing out of the forest and into the clearing.

As the bull's pounding hoofbeats got closer, the friend in the front said, "O.K.! Lets get out and shoot him!"

After a moment that seemed like an eternity Roscoe who's in the rear half of the costume shouted, "THE ZIPPER IS STUCK! WHAT ARE WE GOING TO DO?"

The friend in the front replied, "Well, I know what I'm going to do. I'm going to start nibbling grass, but you better brace yourself."
