A just launched Dominoes campaign, For Real, includes clips from such famed videos including Chris Crocker's Leave Britney Alone, the elephant on the trampoline, car skating, the puking Swedish hostess and, yes, 2 Girls 1 Cup. (Don't worry. Not the gross part)
Not all of these videos are "official" of course as some are not on the Domino's YouTube channel nor anything the brand would approve. We suspect some YouTubers are just having a bit of fun with the campaign inserting whatever they choose into the commercials doughnut hole.
