Lyric discussion by Mr. Bacon 

Cover art for Ana Ng lyrics by They Might Be Giants

This is about a guy's idea that his true love lives on EXACTLY the opposite side of the earth. Vietnam is that place. "her voice is a backwards record" = the garbled craziness of the vietnamese language. "humid air" = vietnams incredible humidity. "water spirals the wrong way out the sink"= the water above the equator spirals clockwise; below: counterclockwise. "still haven't.. ...majestic presence"=they haven't met. Think about it.
