I talk to my grandma once a week. On our last conversation, she informed me her church was having a crusade.

Me: What do you mean by crusade?

Grandma: Don’t you know what a crusade is?

Me: I know what it means in a historical sense, but I doubt a bunch of Oklahoma Baptists are about to invade the Levant on Sunday night.

She thought that was highly amusing.

Also, a crusade is a fancy name for a revival.
