We've endured two weeks with no new Glee and here's our reward: Darren Criss and the gang singing Katy Perry's ""Last Friday Night (TGIF)"" in the choir room. The thing about Perry's songs is that they always sound like good clean fun, but they're really about getting wasted and acting like a drunken idiot. This one even throws a menage a trois into the mix. Even so, it's pretty easy to forget because our gang gets pretty cute and bouncy (minus the weird part where Rachel slaps Blaine on his rear).
Glee returns Tuesday, Nov. 1 at 8 p.m. on Fox.
