Carl Sagan, Richard Feynman, Neil deGrasse Tyson and Bill Nye, sing to us (auto-tuned in a way that I actually don't hate), in We Are All Connected*. *Possibly NSFW owing to sidebar video links. Something similar was mentioned here previously.

A still more glorious dawn awaits
Not a sunrise, but a galaxy rise
A morning filled with 400 billion suns
The rising of the milky way

Cosmos: A Personal Voyage premiered on PBS on September 28, 1980. (Previously). With Carl Sagan as guide, on a "cosmic journey across space and time," on a "spaceship of the imagination," few shows inspired as many people to investigate science, many of whom went on to be scientists. [more inside]

Carl Sagan's Baloney Detection Kit. Yeah, seems pretty faultless to me.

Sometimes a kind of existential perception of the absurd comes over me and I see with awful certainty the hypocrisies and posturing of myself and my fellow men. Carl Sagan commenting (circa 1971) on an experience he had while high on Cannabis over at Marijuana-Users.com. One of the only efforts (along with Cannabis Consumers) to get people to "come out" and help remove inaccurate stereotypes from the mind of the public.
