I thought this was going to be about getting tricked to sell subscriptions to "Grit". There used to be comic book ads from the 1950s to the 1980s that got kids to go door to door to sell subscriptions to a newspaper/magazine called "Grit". Supposedly, if you sold a lot of subscriptions you could get a free bike or a stereo or something.
