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 National Park to study the bears. Finally, their
requests were granted, and they immediately flew to New York and
onward west to Yellowstone.

They reported to the ranger station, where they were told that it was
the grizzly mating season. It was too dangerous to go out and study the
animals. Pleading that this was their only opportunity for study, the ranger
finally 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.

Fearing an international incident, the rangers mounted a search party. They
found no sign of the missing men and the camp was completely ravaged.

The search party followed the trail of a male and a female bear. When the
female bear was found, it was decided they must euthanize the animal to
determine if it had eaten the scientist.

The bear was euthanized and its stomach opened - the remains of the Russian
scientist in clear view.

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

The other ranger responded, "Of course, the Czech is in the male."
