Happiness is a warm puppy.

All his life he tried to be a good person. Many times, however, he failed.
For after all, he was only human. He wasn't a dog.

Happiness does not create humor. There's nothing funny about being happy. Sadness creates humor. Krazy Kat getting hit on the head by a brick from Ignatz Mouse is funny. All the sad things happening to Charlie Chaplin are funny. It's funny because it's not happening to us.

Just remember, when you’re over the hill, you begin to pick up speed.

Oh yes, I'm at my happiest when I have a good idea and I'm drawing it well, and it comes out well and somebody laughs at it.

I think I've discovered the secret of life -- you just hang around until you get used to it.
