Firstly: Is there some sort of cute tomboy ukulele thing going on? you've already met Molly the ukulele girl.
But now I've also found Julia the ukulele girl.
My heart is torn.
Secondly: random people getting down to "Single Ladies" by Beyonce. (Or is it the Beyonce alter-ego on account of the robot hand? I'm so out of touch.)
I would pay money to be able to shake my ass like that. Seriously.
I love it. You go, internets.
