“Participation - that's what's gonna save the human race.”

“I’ve never sung anywhere without giving the people listening to me a chance to join in - as a kid, as a lefty, as a man touring the U.S.A. and the world, as an oldster. I guess it’s kind of a religion with me. Participation. That’s what’s going to save the human race.”

“Saving the human race is a frantic one. Or a tedious one. It all depends on what stage of the process you're taking part in.”

“I believe that the only way that the human race is gonna survive is to start colonizing space and setting up colonies on the moon, and then space stations.”

“It's all well and good to save the human race. You could say I'm in favor. But you might want to pay a little more attention to what's right in front of you.”

“They're gonna' keep chickening us, that's what they're gonna' do! They wanna' crack us up! ”
