Comedy Central is a coy little minx of a network. They flash us just the tiniest glimpses of what we really want and we're forced to come clamouring after them until The Comedy Central Roast of Charlie Sheen finally airs on Monday, Sept. 19. Now, we're getting a little taste of the two people at Sheen's roast who can rival him on the crazy scale. First up, Mike Tyson mumbling something unintelligible that may just put his quips on par with the Situation's performance during the Trump Roast. Then, we get a taste of William Shatner's tounge-lashing for Sheen, and from what we can see, there's a whole lot more where that came from. Enjoy -- though if you're at work, headphones are advised as the audio for both of these clips is a bit NSFW.
