Some ideas for inducing guilt

I think I might be able to even further my techniques for guilt-tripping. Here are a few:

1.  It looks like many people have a hidden feeling of avarice. I think that if i give sermons on the horrors and evils of greed, I'd make the most money.
2. I've seen a lot of people put faith in the bones of saints. I know those are expensive (and therefore I wouldn't make much money off of them) but the ignorant people don't need to know that this bone of Saint "Pollus" is really just a bone of the piece of chicken I had last night.
3. I noticed that when I throw in a lot of biblical references, it really makes the crowd emotional. I think that it would be a good idea to start each sermon with a slew of them that relate to my topic.
