Bernoulli would have been content to die
Had he but known such _a-squared cos 2(phi)!

You can grovel with a lover, you can grovel with a friend,
You can grovel with your boss, and it never has to end.

(chorus) Grovel, grovel, grovel, every night and every day,
Grovel, grovel, grovel, in your own peculiar way.

You can grovel in a hallway, y

In a cauldron bubbling, with eyeballs afloat,
A witch makes her potion on an old, creaky boat.
Ghosts waltz through the moonlight, all silly and spry,
While goblins in costumes steal candy—oh my!

With cackles of laughter and shrieks full of glee,
We dance under shadows, wild, bold, and free.
Be yourself—a specter in disguise,
Where courage blooms and freedom flies.
