Many big sports matchups dotted the holiday weekend — Venus vs. Serena, Yankees vs. Red Sox, Nadal vs. Federer. Another one could be thrown into the mix — Kobayashi vs. Chestnut. Unfortunately. Nathan’s Hot Dog Eating Contest, televised by ESPN, has grown into a big part of the July 4 holiday. This gluttonous battle between the former champ, Takeru Kobayashi of Japan, and current champ, Joey Chestnut of the U.S., may soon turn into this decade’s Ali-Frazier. The interest in this event increases each year and will only get bigger after this year’s dog-off won by Chestnut. I’ll bet a few barbeques on Friday had fools trying to see how many dogs they could ingest in 10 minutes. I’ll admit I want to know who won each year and how many hot dogs were eaten; I just don’t want to watch it. As soon as one of those buns gets dunked into water then slopped into someone’s mouth, I’m crossing off frankfurters from my July 4 menu. America is known for baseball, hot dogs and apple pie.
