Hey party people, are you ready for another installment in The Lonely Island's Wack Wednesdays series? This time the comedy trio has released a dance rehearsal video for their song "Go Kindergarten," featuring Robyn. That's right, Robyn is getting in on the action. Sadly, none of them are actually in the video, but there are some sweet dance moves and ridiculously random full-screen hashtags (#SorryWrongText, #MollyRingwald), à la Robin Thicke's popular "Blurred Lines" music video. At one point, they even give a nod to their inspiration, hashtagging #Thicke.
