Dumpling eating contest at the 2010 Rhode Island Dragon Boat Races and Taiwan Festival. The entry fee was $10, and the goal was to eat as many dumplings as possible in 2 minutes. The winner takes home a cash prize of $100. John returns as defending champion of last year's contest at which he ate 36 dumplings.
This is the full video of the whole contest. You can see a sped-up/edited version in the Pawtucket Festival Montage Video (vimeo.com/14530021). I realize this is a long video. If you just want to see John, he is in Group 2 starting at 2:00 in this video.
