Ernie and Denny went hunting and got lost. Ernie said to Denny "I heard that if you get lost you should fire a shot in the air and someone will come and rescue you". So Denny fires a shot in the air and they wait...and wait... Nobody comes. Finally Ernie said he doesn't think anyone is going to come and maybe they should fire another shot in the air. Dennny said "I would, but that was my last arrow". :p
