If you ever answer scam likely calls what are they usually about or they try to "say" to you?

I only answer them if I'm bored and have time on my hands. I will listen to them trying to scam me, play along with the scam, usually they want to fix my computer or something so I usually press a few buttons on my microwave and tell them all about Jesus. I figure they need to hear about him even more than everyone else.
