Just How Gross is Double Dipping?
How disgusting is double dipping, really? Researchers at Harvard were inspired by the character of George Costanza in a 1993 episode of Seinfeld in which he is caught “double-dipping” a chip at a wake. Double-dipping, for those unaware, is when one dips a chip, takes a bite, and then dips their chip again. The other characters, horrified by George’s behavior, said that his act was akin to putting his entire mouth on the dip.
But does science support George or the other characters in this debate?
