Is this like a joke? Guy looks like he is chucking horseshoes.

Its like fukin magic.

Wakefield could be pitching for 20 more years if he can still throw the knuckleball effectively.

It hurts your friggin knuckles. I'd be surprised if he doesn't get a bad case of arthritis in his throwing hand eventually.
