It's raining, and you're getting drenched. You don't have an umbrella, and there is nowhere to hide from the rain. Suddenly one of the local cult members rushes to you with an umbrella handle.
"Here, here's an umbrella! Use it! By the way, have you heard of our Lord and Savior...?"
Sneaky! Cult members are usually very polite when they try to convert you to their religion. Then they bring you to their temple, get you to kneel before their altar, and the next thing you know you're one of them, looking for the next victim.
