Noon Nathan’s Famous International July Fourth Hot Dog Eating ContestThis annual wienerfest has taken on the gravitas of the Thrilla in Manila after last summer, when upstart eater Joey Chestnut toppled reigning champ Takeru Kobayashi by scarfing down 66 franks to the six-time winner’s 63. Adding lighter fuel to the fire is the fact that the International Federation of Competitive Eating has trimmed the contest time from 12 minutes to just 10. What’s next—accusations of Mylanta doping?
