Back in 2014, the Seattle Symphony decided to mix things up a little by inviting Sir Mix-A-Lot to perform on stage with them. Did they know at the time he'd invite nearly the entire crowd up on stage to join him for a rendition of Baby Got Back? Possibly.
Did anyone know that one woman from the audience (in the black dress) would lose her mind on stage? I'm guessing her children probably didn't...and they're still probably hiding their heads in shame. But, come on, isn't one of the best things about having kids is getting to embarrass them? At least she has the moves to back it up!
