Someone in Japan must be paying attention to super-kawaii Korean rappers, because here's tween idol group Prizmmy☆ ripping off the megaphone-wielding e.via from "Shake!" (minus the booty-shaking, of course, but with rapping). Skip to 0:54 if you're in a hurry or can't stand squeeky, autotuned Japanese schoolgirls.

P.S. One arama commentator says "Damn, wish I was even fractionally this cool when I was in elementary school."
