Riot kill

Some sister, some sister you are
Trapping your kid sister in a jar.

I've got the butterflies, I've got the butterflies
So here's an X-X-X-X chromosome and "Y-Y-Y-Y?" you ask me
Well you know: I'm mad too. As mad at them as I'm mad at you.
I'm a mad scientist.

Here's my new random selection
And you've missed her, you missed her by far.
So much for your little ploy to be a star.

I've got the butterflies, I've got the butterflies
So here's an X-X-X-X chromosome and "Y-Y-Y-Y?" they ask me
Well you know: I'm mad too. As mad at them as I'm mad at you.
I'm a mad scientist.
