Yeah this is not on topic, but here it is anyways...from the NY Times (may require login):
“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.and at Clemsen University:
The power of popular culture I guess.
The team of nine students instructed volunteers to take a bite of a wheat cracker and dip the cracker for three seconds into about a tablespoon of a test dip. They then repeated the process with new crackers, for a total of either three or six double dips per dip sample. The team then analyzed the remaining dip and counted the number of aerobic bacteria in it. They didn’t determine whether any of the bacteria were harmful, and didn’t count anaerobic bacteria, which are harder to culture, or viruses.
