The printed version of Cosmos has a lot of great anecdotes there wasn't room for in the TV series. One of them goes something like this.

*Observatory telephone rings*

Caller: "I need to talk to an astronomer right away!"

Sagan: "Go ahead."

Caller: "I just saw this weird thing in the sky and it was all hazy and you could only see it out of the corner of your eye."

Sagan: "That was Comet (something). It's really bright tonight."

Caller: "Oh. What's a comet?"

Sagan: "It's like a giant snowball in space."

Caller: "A space snowball? You're making that up! Let me talk to a real astronomer!"

Ah, the joys of footnotes.
