OUR annual national snacking binge is almost here. It would take a very large bowl indeed to hold all the guacamole mashed from the more than 100 million avocados that are consumed on Super Bowl Sunday. (My rough calculation gives a hemisphere bowl 20 yards in diameter and 3 times the height of the goal post crossbars.) And guacamole is just one of many dips that will be shared around the TV.

Just in time, a scientific report has some new findings that may cause football fans to take a second look at that communal bowl of dip.

The study, to be published later this year in the Journal of Food Safety, is the only one I’ve ever seen to proclaim that it was inspired by an episode of “Seinfeld.” It was conducted as part of a Clemson University program designed to get undergraduate students involved in scientific research. Prof. Paul L. Dawson, a food microbiologist, proposed it after he saw a rerun of a 1993 “Seinfeld” show in which George Costanza is confronted at a funeral reception by Timmy, his girlfriend’s brother, after dipping the same chip twice.

“Did, did you just double dip that chip?” Timmy asks incredulously, later objecting, “That’s like putting your whole mouth right in the dip!” Finally George retorts, “You dip the way you want to dip, I’ll dip the way I want to dip,” and aims another used chip at the bowl. Timmy tries to take it away, and the scene ends as they wrestle for it.
