What do the world's fastest runners, New York City's poop and quicksand have in common? We're not sure either.

In this episode we ride along on New York City's poop train to find out what happens to poop once it's, well, pooped. Then, we travel to Kenya where legions of athletes, sports gurus, and scientists have tried to figure out why a specific tribe has long-dominated long-distance running. And lastly, we ask why quicksand -- once a real fear -- no longer scares an 8-year-old.

***Poop Train. Ever wonder what happens to all of New York City's poop? So did we. 

***Cut and Run. Kenyans have long-dominated long-distance running; breaking records, winning Olympic medals, and stupefying sports gurus along the way. So what is it that makes Kenyans so darn fast? 

***Quicksaaaand! Long was it that quicksand gripped our hearts and imagination with fear. But these days, quicksand can't even scare an 8-year-old--why?
