His name is Death. But not just a Death ;)
And who is Mort?
Shortly, Mort has been one of persons who are more dangerous than a bag of rattlesnakes. He wanted to understand the logic of the right ruling the universe. It's a difficult task, because such thing does not exist. When the Creator was making this world, he had plenty of excellent ideas, but making it understandable didn't came to his mind.
ME. YOU. GODS. GOOD, ISN'T IT?
I recommend.
