When people first stood on two legs.
When Snoopy first stood on two legs.
When the head of a troupe of actors said, “Shakespeare if you are determined to act write me a play and I’ll give you a part in it.”
When Thomas Edison got tired of cleaning oil lamps.
When Queen Elizabeth thought, “I need a husband like a fish needs carriage.”
When one cave dweller said to another, “Don’t you think that wall would look better with a little color on it?
When a Pharaoh first said, “How can I be sure people will remember me?”
When Moses, while in the desert, said, “Lost? What do you mean, lost? I’ll have us out of here in no time at all.”
What moments in the development of civilization do you think warrant commemoration?
