I love this bizarre little song.

A quick summary of the storyline:  the singer is addressing her ex-boyfriend, whose new girlfriend has schemed to get him to take her to Paris - the implication is that he'll propose in the city of love.  And:

While she's in anxious anticipation,
I really hope you have a horrible vacation ...

Mon Amour

The combination of the quirky lyrics with the instrumentation just makes me grin every time.
