Muhammad Ali was the baddest man on the planet.

Muhammad Ali was the greatest boxer I've ever seen. No offense to Mike Tyson, or Mr. T. Ali was amazing inside the ring and damn funny outside it.

Some classic lines coined by Ali include:

• It's not bragging if you can back it up.

  If you even dream of beating me you'd better wake up and apologize.

Apparently Muhammad Ali could sing a little too. Check out his rendition of Stand By Me and the amazing video that goes with it.
