#17: Gotta Catch Em All
Suppose you’ve lived in America or Japan any time in the last twenty or thirty years. In that case, you have likely been unable to escape Pokémon: either you were playing it, or you had a child in the family who would talk your ear off about steel-type Pokémon if you held still for more than eight seconds.
So Pikachu was an intrinsic part of pretty much everyone’s life, and yet a lot of people misremember a certain detail about him. This one isn’t too surprising if you think about it; he’s got black on the tips of his ears, so it’s natural for some people to assume he’s also got it on his tail.
