How animals eat their food (video)

Here is a funny video on youtube about a guy imitating how some animals eating their food (such as cows, whales, etc) with some hilarious results.  

I have never seen anything like this video before and I do like how the other guy did not seemed to be phased by the person imitating the animals.  By the way, I don't recommend trying this on a date or in the school cafeteria (you will probably get yourself in trouble if you try this).
