Six-time consectuive champion of Nathan's Famous hot dog eating competition and hot dog world record holder Takeru Kobayashi is probably in tears this weekend.  Kobayashi's world record of 53 3/4 hot dogs and buns was shattered by Joe Chestnut of San Jose, CA.  Chestnut managed to stuff himself with 59 1/2 "HBDs" in 12 minutes at the Southwest Regional Hot Dog Eating Championship in Arizona.
