This fun Tumblr thread imagines a world where a man possesses the ability to see people's threat level (as numbers 1-10, with 10 being most dangerous) above their heads. From there, we see a fun scenario created where the guy is able to identify iconic characters like Clark Kent, Bruce Wayne, Wonder Woman, and Robin for what they really are. This inspires quite the funny picture. It would be rather confusing to see a whopping 10 above a billionaire's head.
For some more gold from Tumblr, check out this fun thread that takes a look at the logistics behind Davy Jones' curse.
