They came, they saw, they party rocked — and then they dipped.

A quiet bingo night at a senior community center is interrupted by an exuberant trainer and a familiar dance hit by party rocking duo LMFAO in a current commercial for European eyeglasses company Specsavers.

We don’t know what’s worse in this situation: the fact that parents, yes, parents — those people whose goal in life is to embarrass you no matter how old you you are — joined together for a 10-minute flash mob, or the fact that they chose to do it to LMFAO and the Black Eyed Peas.

Adele, LMFAO and Rihanna lead the nominations for the 2012 Billboard Awards, which take place at Las Vegas’ MGM Grand and will be broadcast live Sunday May 20 at 8 PM ET on ABC.

It sounds like a few LMFAO fans will be especially sorry for party rocking a little too hard. Massive crowds at a series of free concerts in Indianapolis caused multiple reports of revelers getting trampled, with 11 confirmed injured.

It’s hard to imagine Top 40 radio without the ubiquity of LMFAO‘s dance anthems — in part because they’ve been on the charts pretty much since their inception. As a result, the Day-Glo duo are on their way to making Billboard history.
