I was thinking they might have Nakamura wear a cup in anticipation of AJ getting pissed and trying to nutshot him, but that would make AJ look really stupid if he also wasn't wearing a cup.

Part of me thinks it'd be funny if they did it like an episode of Grounded for Life where these guys were boxing and just kept dickpunching each other the whole match, but that doesn't really fit in a "dream match"
