"don't think zebras"

[Joel S. Berson]

Not in the Yale Book of Quotations nor a couple of recent Oxford
books of quotations.

"When you hear hoofbeats, think horses, not zebras."

Attributed in the NYT by Michiko Kakutani (Books of the Times, Feb.
16, 2010) to "the character Gil Grissom in 'CSI: Crime Scene
Investigation'", and characterized by her as succinctly put by him.

This must go back earlier. I've heard it attributed to real doctors
but I don't know how long ago.

What say the industrious CSInvestigators?

Joel
