That's the female

A couple of hunters from Prague are out hunting, and an emormous bear runs up and in a single gulp devours one of the hunters.

Miraculously, the swallowed hunter remained alive, trapped in the belly of the grizzly. The other hunter runs back to town and organizes a rescue party which heads back to the woods armed with torches, guns, spears, etc.

Soon they spot two bears on the horizon and everybody starts shooting at the bear that's closest to them.

"No, not that one," shouts the surviving hunter, "That's the female."

"The Czech is in the male."
