The version of NBA Jam you were never supposed to hear (NSFW)
UPDATE: Confirmed as fake by the Jam announcer, Tim Kitzrow. Disappointing, but still good for a few giggles.
Apparently the announcer for NBA Jam recorded a few "spiced up" lines as a joke for the team working on NBA Jam way back when that if they had made it to the ESRB? You'd have an M rated basketball game.
