That line is probably my favorite from a song stuffed with haunting lyrics, Tom Waits’ “Dead and Lovely.”
That description punches. It offers a commentary both about relationships in general and this man in particular. It speaks of danger and the need for constant vigilance around him. It implies that he is a force of nature (or mechanics) capable of destroying anyone unwary. It hints that he has a lulling, seductive power. And it says more in ten words than this entire paragraph.
I love that line. And I love the song. It’s dreamy and tragic; I can listen to it on repeat for my entire commute to work, and it puts me in a trance.
Here is a fan-made video for the song, just so you have something more interesting to look at than the album cover.
