I had loved the of Montreal cover of this song by the now broken-up Gorky's Zygotic Mynci (what a name), but for some reason I hadn't listened to the original version up until a couple of months ago and I fell in love--I like it more than the cover. 


The last verse repeats the lines and then we'll be married. and then we'll be happy and I have always thought of it as a sort of cynical nod to the Beach Boy's Wouldn't it be Nice?  Not sure if that's really the intention, but I always liked thinking of it that way.
