This is one of my favorites:
"An archaeologist is the best husband any woman can have: The older she gets, the more interested he is in her." — Agatha Christie

"Communism will never work in America because people like to own stuff."
"There is more stupidity in the world than hydrogen, and it has a longer shelf life."
