Takeru Kobayashi INHALES Whole Pizza at Super Bowl Party

Know why your Super Bowl party sucked? Because competitive eating champ Takeru Kobayashi wasn't there ... eating an ENTIRE PIZZA in one minute flat.

Kobayashi's rep tells TMZ, some guy on Long Island paid the human garbage disposal to make an appearance at his 40-person Super Bowl party last night ... and perform an eating challenge.

Kobayashi decided to attempt to break his world record for scarfing a 12-inch pizza (1 minute 9.36 seconds). In the clip, Kobay downs the 12-incher in 60 seconds flat ... but it wasn't an official event, so it doesn't count as a new record.

His rep wouldn't comment on how much he was paid -- but Kobay's publicized rate for lunch or dinner appearances is $1,500.

Kobayashi also accepted a beer chugging challenge from a random party goer yesterday ... but we were a little disappointed with TK's performance.
