At the beginning of the video, you can saw 2 cows standing still in front
of something strange. The cow on the right said it's a crocodile while
the cow on the left said it's just a tree trunk. The cow on the right used
several ways to proved that it's a crocodile like throwing a stone at it,
touching it with a stick, throwing water on it but the cow on the left
insisted so the cow on the right decided to climb on it. A few seconds
later it is ate by the crocodile and the cow on the left changes its
mind and said it is a crocodile so another cow appears and said it is a
tree trunk.
