Listen to more Metal. Iron Maiden and Metallica are not the garbage that people think of when they think "Metal", ie, mindless noise with people screaming. In fact, a lot of it isn't. Oh and Dickinson is the greatest singer ever, just wanted to throw that out there.
Michael Scott. I don't find the British version funny, which I'm pretty sure is 100% down to me not being British.
Dwight Schrute or Gareth? I forgot what his last name is...
Gareth is actually going to be on the best show on tv, Game of Thrones season 3 btw. Should be interesting.
