Why does this make me think of Bugs Bunny and "Never worry, never fear, Robin Hood will soon be here..."

So, Ole and Knut go hunting in the swamp. Ole says to Knut, "If you get lost, just shoot three times in the air, and I'll come getcha."

Five days later, Knut comes dragging out of the swamp and finds Ole drinking in the bar with the sheriff and the search team.

"I did what you told me," Knut says. "I shot three times in the air every hour or so, but it didn't work. Whatsa matter? Couldn't ya see my arrows?"

I got one of these "Mega Sound Blasters" <http://www.amazon.com/Sounds-X-treme-Mega-Sound-Blaster/dp/B000FAKFFK> from American Science & Surplus- currently out of stock, but they seem to get them in every so often. It's a small plastic horn (about 3 inches long) that makes a deep sound above the threshold of pain when you blow into it! Claim is it can be heard a half mile away or more. I don't know how sturdy it is, because I've only tried it once - that was enough!
