Oh my god, I am SO FUCKING RELIEVED to know that I am not the only one who is TOTALLY OBSESSED with this commercial!

Addendum: Wow, I'm a retard — I just got the whole punny joke of the song: that the Tender Crisp Bacon Cheddar Ranch is not only a sandwich but also a place (a ranch). Which is why they are singing a song about it. Shit, that is HILARIOUS.
