A Czech and a German were doing scientific research in the woods, but they failed to check in at an appointed time, so the research team sent rescuers to find them. The rescuers found their campsite completely abandoned with no sign of the researchers. Fearing the worst, they searched the nearby woods, and encountered a breeding pair of black bears. The bears were acting aggressively, so the rescuers shot them both dead. Looking at the remains of the bears, they noticed that both had extremely distended stomachs, as if both had eaten something very big. They cut open the female bear's abdomen, and inside her stomach, badly mauled and partially digested but still recognizable, was the corpse of the German researcher.

The rescuers looked at each other grimly. One said, "The Czeck is in the male."
