Honestly, in my mind it’s a complete toss-up. The cast of Glee does kill their a cappella rendition of “Teenage Dream”, but Katy Perry’s music video is also pretty legendary. I’m putting it to a vote: whose “Teenage Dream” will make you go all the way tonight (no regrets, just love)?
Also: Katy Perry named her cat “Kitty Purry”. Thought you should know.
