[Quiet Man Cometh]

So I'm watching TV (no, really?) and on comes a Telus add with two cockatoos waving their crests around as the riff starts for AC/DC's "Thunderstruck." I love the add, but all because of the song (well, that and the black cockatoo which I also found out actually exists :)).

So I've gotta ask, regardless of the actual song, what songs strike you having the best supreme awseomeness of openings? (I think I've watched Jack Black movies too many times.)
