Not all sharks are 20ft and 2 tons. You could very well hold up a small shark. Since sharks have been found with soda cans in the stomach cavity, one "could" conclude that a shark would eat leaves. There are also plenty of trees next to the ocean. I'm sure this question would be an epic fail if you were holding a 2 ton shark up to a tree in Montana.
As far as the lion is concerned...I'm fairly sure I would understand the lion speaking English way before I would understand a person speaking German.
entertaining Lizzie, throw something else up here....lol
anybody up for the "tree falling in the woods" debate... Or how to escape from the middle of a lake covered with frictionless ice(barring wind resistance of course)?
