Believe it or not, it's been 15 years since Britney Spears declared that she's just "not that innocent" in her hit "Oops! . . . I Did It Again." And now the music video is grabbing headlines all over again. In a viral video made by sound engineer Mario Wienerroither, sound effects give us a funny take on what Britney and the crew heard when she filmed the clip in her iconic red jumpsuit. The epic background music has been replaced with the squeaks the latex piece may have made as she busted out her now-classic dance moves. Check out the hilarious video, above, and then watch the original clip, below, to relive one of your favourite Britney moments of yore.
