The hurdles are undoubtedly one of the most entertaining events in the Olympics, and not just because of one athlete's sexy warm-up routine.
As Jimmy Fallon pointed out on "Late Night" Friday night, the potential for mishaps also makes the hurdles sort of like an Olympic version of "America's Funniest Home Videos" (or FAIL compilations, if you want to be 2012 about it). For that, he wrote them a thank you note.
Fallon's other thank you notes this week were heavy on the inanimate objects, including phone books for combining the two things no one uses anymore. Luckily, they still make pretty good door stops. Watch the video above.
