George Carlin:
Let me tell you about endangered species, alright? Saving endagered species is just one more arrogant attempt by humans to control nature. It's what's got us in trouble in the first place, doesn't anybody understand that, interfering with nature. Over 90% of the species that have ever lived on this planet are gone, they're exctinct. We didn't kill them all. They just disappeared. That's what nature does.

Douglas Adams:
We haven't even finished burying the artificial dinosaur skeletons in the crust, yet.

Graham Chapman:
Eee, ecky thumb.
