Years ago I saw this video of a guy with a disability where his legs had grown essentially backwards, so his gait looked, let's say "non-standard." It's rare, but it happens. He lived somewhere in Latin America and the video was him getting body painted like a demon and the popping out of alleys and around corners, chasing people. Everyone, adults and kids, lost their minds with fear. I can't find the video, but temping the first half of fight or flight like that seems like a bad idea.
