Segment #6. Skeptical Quote of the Week
"If all your friends jumped off a bridge, would you jump too?"
"Oh jeez. Probably."
"What!? Why!?"
"Because all my friends did. Think about it — which scenario is more likely: every single person I know, many of them levelheaded and afraid of heights, abruptly went crazy at exactly the same time… …or the bridge is on fire?"
- Randall Munroe (xkcd)
