Nat and Kat, The Amazing Race 17
It only took 17 seasons, but The Amazing Race finally crowned its first all-female team winners, and it could not have gone to a more deserving team than these doctors and name-rhyming BFFs. The definition of "calm, cool and collected," they never broke out into hysterics, let alone a sweat, when things weren't going their way or when faced with a tough challenge. Extra points go to Kat, a vegetarian for 22 years, for not complaining, but instead buckling down and eating sheep's head to win the Fast Forward. We love meltdowns, feuds and tears as much as anyone, but there's something to be said for composure and steadiness.
