The answer is not "the Giants! (We can only hope here in NY)." Wrong question.
No, the question I had in mind was: Is Double Dipping Harmful to your Health?
This question was first posed in a Seinfeld episode back in the day, as explained in an article in the NY Times yesterday (Dip Once or Dip Twice?). Apparently, the "double dipping" meme was a brainchild of one of the show's writers.
According to the study mentioned in the article, yes it is.
[The study found] that three to six double dips transferred about 10,000 bacteria from the eater’s mouth to the remaining dip.
The professor who ran the study at Clemson University said:
“The way I would put it is, before you have some dip at a party, look around and ask yourself, would I be willing to kiss everyone here? Because you don’t know who might be double dipping, and those who do are sharing their saliva with you.”
This is why the Times rocks and us tech PR folks needs to stay attuned to the latest in science news.
