Alexa J haha same thing here. My best friend is a really preppy girl so she used to annoy me all the time by singing this song, but after having heard Darren/Blaines version, I'm in love with it.
Yeah we dueled on tabletops and we broke into Gringotts think they kissed but I forgot last friday night yeah neville rocked out with a sword so he cut the final cord and harry blew up the dark lord LAST FRIDAY NIGHT
I used to watch the Katy Perry video all the time and I loved the part that Darren played so I memorized it (but I didn't know Darren at all) then I watched glee and I was like that's the guy from Katy Perry's video. Don't forget Kevin Mchale, he was the "Nerdy boy".
