I used to see a lot of ads for religious counseling lines on one of the TV channels I watched as a kid. I somehow misunderstood these as offering a hotline directly to God. Not being particularly religious, I assumed these were some kind of scam in which there would be someone on the other line who would pretend to be God. I thought it very silly that people were taken in by what I thought was a very transparent hoax.
