There was a time when man was friends with lizard, rat, dog, snake, lion, tiger and goat.
The lizard likes to look at what he does and nod (okay i'm watching) says the lizard.
The dog likes to stay around him.
The lion roars as he passes him, (Whats up big meat says man to the lion), the lion wags his tail.
Man and animal could understand themselves.
But goat was one interesting animal man observed.
Goat when told to do something refuses and does whatever he wants.

One day, man was eating grass and goat was anxious to talk to man but didn't know how to talk to man because man could not understand him.
So goat sat near man while man was eating grass
You eat every thing eatable and you still eat grass says goat to man that's why i like doing anything i want to do.

What was man's response?

I am an omnivorous and you're not
