OT, but interesting
 

Someone asked Randall Monroe, the creator of xkcd, "If you stripped away all the rules of car racing and had a contest which was simply to get a human being around a track 200 times as fast as possible, what strategy would win? Let's say the racer has to survive."

Monroe answers it here: http://what-if.xkcd.com/116/

If you weren't already a fan, go back through recent "What If" entries, and the recent "xkcd" entries. You'll be lost for hours. :-)
