What's to be expected given the title track, with a hilarious 'nyah nyah!' line on top of the chorus! Give a closer ear to the song, though -- where the reason not to grow up is that it might "mean being like you" -- and the band's core message of having fun and dealing with things as best one can in a stupid society is still there. When the four want to be straight up and perfectly poppy, they can and do with smashing success, with surprisingly mature, emotional lyrics and playing that doesn't rely on all-speed all the time.
