I don't always drink beer

I have had three other lives, but I don't remember anything about them.

People ask me how I became the most interesting dog in the world. I tell them I don't know.

I am not able to leap tall buildings in a single bound, but I can jump really high. And I can prove it.

No one really knows what evil lurks in the hearts of men and other sentient beings, but I have a pretty good idea.

I don't always drink beer, but when I do, it makes me sleepy.
