Flash mob advertising once used to be fresh, innovative and fun. Now they’re just boring.

But that didn’t stop Dr Pepper from creating a flash mob advert for their new campaign, says Bitterwallet. – but unlike previous flash mob ads, Dr Pepper didn’t even stick to the rules!

A true flash mob is where dozens or even hundreds of strangers descend on a given location to carry out a pre-planned act, such as to sing a song or perform a dance routine. But Dr Pepper instead hired some singers and dancers and plonked them onto the trading floor of the New York Stock Exchange to sing the Dr Pepper theme tune – badly – as traders looked on in bemusement.

Watch the advert and let us know what you think of it in the comments. After all, what’s the worst that could happen?
