How to stop me singing show tunes

Me (starts singing the title song from Cabaret): What good is sitting alone in your room?

15-year-old: A lot of good, because then nobody would have to hear you singing that song.

Terrific retort. Almost as good as the time I told my brother he looked like an emo and he said, "You look like an emu." I couldn't think of a reply because I was laughing too much, but I am going to put this picture up on the internet. Which will have to do.

I have a much better singing voice than her. That's just a fact.
