I'm sorry, but I honestly can't remember him cutting a 5 minute promo. Can you remind me? Whenever I think of Batista in a non-wrestling context, it's in backstage skits or uttering a couple of sentences in an angry tone during an Evolution promo.
He's only had one real promo in the WWE and that was one to hype his match with Michaels before some PPV. He has cut great promos elsewhere, like in OVW for instance.
