A Russian scientist and a Czechoslovakian scientist had spent their lives studying the grizzly bear.

Each year they petitioned their respective governments to allow them to go to Yellowstone to study the bears. Finally their request was granted, and they immediately flew to Yellowstone.

They reported to the ranger station and were told that it was the grizzly mating season and it was too dangerous to go out and study the animals.

They pleaded that this was their only chance, and finally the ranger relented.

The Russian and the Czech were given portable phones and told to report in every day. For several days they called in, and then nothing was heard from the two scientists.

The rangers mounted a search party and found the camp completely ravaged, with no sign of the missing men. Following the trails of a male and a female bear, they finally caught up with the female. Fearing an international incident, they decided they must kill the animal to find out if she had eaten the scientist. They killed the female and opened the stomach to find the remains of the Russian.

One ranger turned to the other and said, " You know what this means, don't you?" The other ranger responded..
