Justin Bieber Has Mantis Shrimp Heritage
We know that Justin Bieber is from Canada, but there is much more to his heritage than maple leaves and hockey sticks. Some scientists believe that his excessive squinting is due to having mantis shrimp ancestry. The mantis shrimp is famous for its incredible ocular abilities, and can see many colors humans don't even have names for. Access to this extended rainbow could cause Justin to be overwhelmed by crazy hues that he can't explain to anyone (like "burple" and "dink"). In response, he squints to let less light in, and thus prevent his brain from exploding.
