Walk out with their belts? Last person I saw do it was Matt Hughes. Wouldn't you think they'd wanna wear it to the octagon?
Because everyone made fun of Tim Sylvia for wearing it everywhere, now they're too embarassed to wear it at all.
There's actually a funny clip of Hughes backstage after winning a title fight. He takes off his belt, and is like "Get this thing off me, I'm starting to feel like Sylvia." Sylvia was standing right there.
