[On if he's ever been booed]
Quinton Jackson: After the fight, I knocked Chuck [Liddell] out, I got booed. I thought it was an exciting knockout, but I got booed, I was like "whoa." That really bothered me after the fight.
[On people challenging him]
Quinton Jackson: I'm hearing in interviews, people calling me out, people in other weight classes calling me out. I got this heavyweight, Kimbo Slice, might be true, might not be true, calling me out. I'm like "hold on dog, you're not even in my weight class, I don't even think you can make my weight class." He don't even fight in my organization.
[On losing his first MMA fight]
Quinton Jackson: I remember sitting down in my apartment the next day with my head down and my legs were sore from all those kicks. I was like "man this guy done whooped my ass." I said, "I cant believe I let this guy whoop my ass" and that made me go out and train hard and I trained my butt off and I got better.
