Two hunters are walking through the woods. Eventually they realize they are lost. The first asks the second what they should do. The second hunter replies : "I heard if you're lost you should fire three shots in the air to signal for help. " So the first hunter fires off three shots and they wait a half hour. No help arrives, so they try again. Another half hour passes, no help. They fire off another three shots. When no help arrives, the first hunter turns to the second and says "we need a new plan. No help is coming, and I'm running out of arrows."
