A Halloween Chorus Line

OFF: One! chorus line of people,
Dancing till they make us stop,
Grandpa: Too!
Everyone: Many dancing people,
Covered with blood, gore and glop.

Just one sniff of that fog
And you're inside out,
It's worse than that flesh-eating virus
You've read about.

Vital organs, they are what we're dressed in.
The family dog is eyeing Bart's intestine.
Hap-py Hal-lo-we'en!
