Brock Lesnar couldn't/wouldn't/won't beat Fedor Emilianenko.
And Steve Austin would Stunner his big Hulk ass.
Seriously though, Brock Lesnar is incredible but people are awe-struck by his body (and how he is deceptively fast etc.). Let's talk about how good he is in a few years, after he's had as many fights as the guys he's beaten so far.
Bruce Lee has wild fans and was a film star, but he was also one of the greatest martial artists of the twentieth century - people forget that. Personally, I think even someone like Jet Li would (have? - when younger) put up a hell of a fight - he too may be an actor, but he is a hugely talented martial artist.
Even more seriously, this is stupid and we all know it too.
And am I the only one who finds this whole Chuck Norris thing incredibly annoying?
It's also a certain 'type' of person who brings it up (that's not really some sort of profiling I'm trying to do, it's just those borderline indie emo kids...). I'm one of very few people I know who had seen a Chuck Norris film before all this rubbish (Channel Five, 9 o'clock movies!), awful though it was.
