This Brazilian man is tone deaf. However, he thought he would attempt to sing scales anyway.

Sorry, but he sounds terrible. He keeps trying but the same exact sound comes out of his mouth! By the time he hits like the 5th or 6th note and the tone is the same we really began to crack up. It's too funny.

Here's the thing. If you know you're not good (or incapable) of doing something, do you still try?
