A few I was thinking about recently:

I truly believed that Dan Hardy was an anarchist punk hooligan during his active years in the UFC. The mohawk, that bandana thing over his face, his walkout music, and that stomp thing he did when being introduced, made him legit terrifying to me as a youngster. I thought he spent his days vandalizing, pushing old ladies over, and setting shit on fire.

I used to think that plexi glass should replace the fencing in the cage. I was positive that the powers that be in the UFC were stupid not to think of it. Now I realize with sweat, blood and god knows what else, it would be a horrible viewing experience for everyone.
