Don't let what Chael says bother you, it's an act. There are 2 versions of Chael Sonnen, the mild-mannered nice guy who is well spoken and the lunatic sociopath that shows up whenever Anderson Silva enters the conversation. He'll say whatever he wants to get attention.
Where is this mild mannered nice guy you speak of? Seems to me anderson silva is not required to send chael off into looney land, anything from ring girls to the weather in cancun will do it.
