bu, bu, bu Brock can't talk. ..

dude can talk just fine when he has points to hit.
Him yelling ranting and raving like he did after he beat Frank Mir wouldn't work in a WWE setting, that monotone almost bored tone works because a cat that talks like that generally has done all the horrible things he's telling you about in his promo so he isn't yelling because he doesn't need to do so to further his point. They've got my interest going for this feud Punk would gain so much from losing than winning IMO.
on a non kayfabe setting I don't think Punk himself would lie and tell you he wouldn't get mauled if Brock had an issue with him
