Dude's an addict. 

How Takeru Kobayashi found himself at a party with a bunch of amped up Bro-types merely using his presence for circus-like entertainment is a story in itself, but that's all really just a sideshow to what goes down here. He's no longer the Great American hot dog champ, but there's not many things more Super Bowl-worthy than gorging oneself with a whole pizza in only a minute. 

In other news, this is clearly one of those cases where a bunch of dudes at said party attempted to exploit Kobayashi's unexplained presence through a mass "I'm hanging out a decently famous person right now" text--in which they'll fail to note that "hanging out"  was simply waiting in line after him for the tray of wings, and ultimately failied to start a conversation because because Kobayashi was actually kind of awkward, and/or is pretty annoyed with being treated as a spectacle rather than a person. Also of note, this sort of treatment every waking moment has nothing to do with the fact that celebrities end up having severe mental health problems.
