Seen here wondering where the hell his toes went, this is a video of teenager Maxwell Day of London demonstrating his Guinness World Record for 'largest foot rotation,' by rotating his feet backwards a full 157-degrees. That is entirely too far to be able to rotate your feet. For reference, mine only rotate far enough back to make me walk duck-footed. If I close my eyes I can still hear the other students and teachers at school laughing and yelling, "Quack quack, Duckers!" as I shuffled by. If I could do it all over again, I would, and I wouldn't be home schooled.
Keep going for a video of Maxwell discussing his superpower.
Thanks to Adam L, who wants to know if that qualifies as a Halloween costume because he's not against breaking his own feet.
