A lawyer invites his cousin from the Czech Republic to come and stay with him in Canada. Soon they decide to go hiking in the woods. Suddenly, a big grizzly bear appears. The bear kills the Czech cousin and then eats him.
The lawyer runs to the nearest village and tells everybody what has happened. The villagers form a search party and return to the forest. They come across some bears and ask the lawyer to identify the one that killed his cousin.
'It's that female bear over there.'
They kill the bear and rip open her stomach, but there is nothing there. They decide to kill the male bear nearby, and when they rip open his stomach, they find the poor Czech cousin.
The lesson: Remember: The Czech is in the mail.'
