[He knows you, Mister Dark and Brooding. Or someone close enough like you.]

That's a pretty backhanded compliment right there, I don't know if I should be sticking with being happy my singing voice isn't too bad, or... no, you know what, gonna stick with being happy about that. [If this was anyone else he'd make a flirty shower comment but... this isn't anyone else.]

But now you have to tell me, is the song stuck in your head, too? Did I pass it along like a terrible cold?
