A Park Ranger friend told me this the other day, its old and not eco-friendly but funny none the less.
Two Park Rangers were walking through the woods spraying the pine trees with a gasoline/water mixture to kill pine beetles. They stopped and set down their sprayers to take a break. The two Rangers looked over and were shocked to see a squirrel drinking out of one of the sprayers. Suddenly the squirrel ran around the sprayer ten times, did two backflips, five somersaults, and fell flat on his back with his legs straight up in the air. One Ranger asked the other "man, what happened to him!?" the other Ranger replied "must of ran out of gas".
