A biologist from the North Pole was showing a new recruit the ropes of a polar bear radio tracking program. The new recruit said, I know how the transmitters work, but I have one question–how do you catch the polar bears in the first place? I bet you use high-powered tranquilizer dart guns, right?Oh no! the experienced biologist replied, we use an ancient Eskimo technique, developed centuries ago. First, we dig a huge hole in the ice. Next, we place a circle of green peas all the way around the hole. Then, we go hide behind some ice blocks and wait. Finally, when a polar bear comes up to take a pea, we kick him in the ice-hole !!!
