There was once a time, in the very recent past, when Mike Tyson was the most feared person on the planet.

He once won the heavyweight championship after 91 seconds, ending Michael Spinks' career in the process. He was the only person ever to knock out Larry Holmes. He bit off Evander Holyfield's ear. He was a b*tch to beat when you were playing as Little Mac in Punch-Out.

Now, apparently, he writes and performs ballads about NBA players. Here's one on Kevin Durant, similar to his recent song about LeBron James, that he performed last night for the first time.

I think I speak for all of us when I say, Iron Mike, dude—have some dignity.
