Amazing that at 34 seconds, that's her longest fight in a while. The last 2 went 14 and 16 seconds. It must be making it hard to market her pay per view fights when they never last. I remember people being really pissed at a Tyson fight that was well under a minute because they paid $60+ to see it.

We have Stewart Brand to thank for those images of the whole earth... It's too bad Tyson is more scientistic in his thinking than actually scientific. Like most television personalities, he sacrifices the rigors of skepticism (which are at the heart of the scientific method) for more popular notions of what sells books (and, now, tickets) which help to promote his "brand."

Guys, this ain't so hard...
You're a racist when you assign more or less value as a human being to people of a certain race (ethnical group) than you assign to yourself because of their ethnicity. There's a difference between saying "Stalin is less worth than M.L. King" (personal opinion) and "white people are worth less than blacks". The latter would be racism.
Prejudice is when you have opinions about people before knowing the facts about them.
Walking up to Mike Tyson and saying "You must have a giant cock because all black men are giants" is a prejudice that may be racist but it assigns positive values. Sure, it's offensive, like telling asian people they must be great at math, but somewhat forgivable. You're an ignorant cunt, yeah, but at least you said something flattering. You racist.
Walking up to Mike and telling him "All black men are criminals" is not only prejudice but also racist. Why? Because calling somebody a criminal is a negative judgement. A generalized negative prejudice towards an ethnic group is a racist way of thinking. Mike was convicted for raping his girlfriend. He is a criminal. Not all black men are Tyson. And if they were, I'd prefer the science variant. You're plain wrong.
Now saying "I bet all black people like listening to R'nB music" is just prejudice. There's no judgement here. Right? Unless you consider "he listens to R'n'B" an insult. How about "all polish people love ice cream"? Did you just imply polish people are all fat?
The difference between prejudice and racist prejudice lies entirely in subtext and context. It's not what you say, it's what you mean.
Prejudice is a tightrope made of blurry lines spanning over a pit of outrage. That's why politicians should not walk that way.
Being aware of differences between race, ethnic groups and talking about is simply being hones and probably not giving a shit about political correctness. We ARE different. That's the interesting part.
What we sadly forget is this: to focus on what we have in common. But somebody already said that way more eloquent than I ever could:
"Hath not a Jew eyes? Hath not a Jew hands, organs,
dimensions, senses, affections, passions; fed with
the same food, hurt with the same weapons, subject
to the same diseases, healed by the same means,
warmed and cooled by the same winter and summer
as a Christian is? If you prick us, do we not bleed?
If you tickle us, do we not laugh? If you poison us,
do we not die? And if you wrong us, shall we not revenge?
If we are like you in the rest, we will resemble you in that.

Of course not surprisingly Tyson won...

Big fan of hers. She's such a tough, skilled badass. She's like a young Mike Tyson, kicking asses and not even bothering to take names later.

The only problem is there's no one who comes close to her level of badassery, so most of her fights are no contest, but her last fight with Miesha Tate was the best ever.

I think Bethe Correia should be a challenge, but we shall see.

As a long-time NPR listener, I applaud Iv_hunter for bringing an air of class and maturity to Videosift with this submission. Too often, Sift is plagued by such low-brow topics as TED talks and the ever-rancorous Neil deGrasse Tyson. By exposing the Sift audience to masterpieces such as "lol horse fart", one is reassured that erudite viewing will never go out of style. Salute', Iv_hunter!
