It's this song.

Don't mind the video, I'm guessing it's a campaign for the student body or something.
Anywho, my friend sent me the link asking me if I knew what it was and I got curious too, cos' it sounds so familiar. I think I've heard this from a commercial before or something.

Anyway, thanks for all the help you guys.

I think it's the opening theme for The Office? (I don't watch the show myself, but I've caught the opening... and the title for the clip said "The Office" looooooooooool)

Looking it up on Wiki, it was written by Jay Ferguson and performed by The Scrantones.

Yes, it was even linked as the suggested viewing of that clip, zero effort investigating.

Haha, I can't believe I didn't catch that.
Thank you! (:
