The line that kills me is "I'm going to dance all over you," delivered mid-fight in Ready 2 Rumble Boxing: Round 2. That's Michael Jackson in the Dreamcast ring, 26 years back, with his real voice dropped to a lower pitch for the part. He was unlockable, and the whole thing was motion captured. Of every celebrity who ever showed up in a boxing game, I'd put this near the top of the list. MIDWAY knew what they had.
