These are my people

Happiness is going to a party were, within 10 minutes of your arrival, someone says (in response to another comment, “What was the monster in Hitchhiker’s Guide that did that?”, and at least five people simultaneously say along with you, “The Ravenous Bugblatter Beast of Traal.”

And later, someone quotes The Pirates of Penzance.

And most of the attendees not only get your Styx jokes, but cracked some of their own.

Yeah. Good times. :-)
