Stevie Wonder

Stevie Wonder isn't really blind. Dude always wears a watch, he goes to a lot of basketball games, he is always on camera looking at people in the eyes, reaching out to hug them before they actually get to him, I'm convinced but I'll never be able to prove it

Here's How To Prove It: Go to one of his concerts and during a pause when it gets quiet just go, "HEY STEVIE" and whip a brick at him.

If he ducks, he's lying. If he doesn't, well, you're basically an asshole and also he still may or may not be blind.
