A primer on competitive eating’s premier event, the Hot Dog Eating Contest, which airs today at noon EST:

1: During the allotted period of time, contestants eat as many hot dogs and buns (called "HDBs") as they can. 2: They're allowed to use a beverage of their choice to wash things down. 3: They must stay in full view of their own, personal "Bunnette" scorekeeper. 4: Condiments may be used, but are not required. 5: HDBs that are still in the mouth at the end of the contest only count if they are eventually swallowed. 6: Puking up the hot dogs before the end of the contest (called "a reversal") will result in a disqualification, unless you do something horrific to make up for it (more on this later.)
