We’ve gathered amazing and surprising facts from the world of Collections. We’re not talking baseball cards and Beanie Babies—we’ve got: glucose, gamma rays, brainwaves, fake art and some very blue Russian. Our panelists:

Tim Ferriss, best-selling author and host of the Tim Ferriss Show, collects antique Japanese saddles for “special occasions.”

Anne Pasternak, director of the Brooklyn Museum, once collected a stomach full of cat food.

Eugene Mirman, comedian and voice of Gene on Bob’s Burgers, collects small failures.

Our real-time fact-checker is A.J. Jacobs, host of Twice Removed, who has some holes in his encyclopedic knowledge.
