I never actually saw it live but I just assume it was all a joke and that Caveman DCJ was trying to make it awkward. I mean the way he shuts the guy down when he's doing the deep action hero voice by saying Tomba doesn't actually talk was so unnecessary I just assumed he was playing it up. Viewing that again knowing that Caveman DCJ genuinely didn't like that guy's commentary just makes it even more hilarious. Good god, I physically recoiled when it I got to that moment again.
