Buddha says:

Better than a mule
Or the fine horses of Sindh
Or mighty elephants of war
Is the man who has mastered himself.

Dr. Seuss says:

I meant what I said, and I said what I meant. An elephant's word is one hundred percent.

Groucho Marx says:

One morning I shot an elephant in my pajamas. How he got into my pajamas I'll never know. (Animal Crackers, 1930)
