This is, like, the best song EVAR [sic].

"I'm Not Gonna Teach Your Boyfriend How to Dance with You" as performed by Darren Criss (HARRY FREAKIN' POTTER) and some other G.L.E.E. (Galactic League of Extraterrestrial Exploration) people.

This song makes me so bloody happy.

The original version is by Black Kids, if you want to go check that out.
