> If, on appropriate occasions, the members tell, enjoy, trade, and/or devise transgressively funny jokes about their denomination, it's a church.

> If such jokes reliably meet with stifling social disapproval, it's a cult.

An interesting definition I totally disagree with. It's the social disapproval that turned any of us into geeks, and guess what - I personally like it that way. Society approves mostly things that are pointless or boring anyway. An example: why do you think HN guidelines advocate against posting mainstream news?
