When I was a kid, I remember a talk radio show my family listened to that was one of those consumer watchdog / product review shows. One of the advertisements that you head a lot back then was for purchasing a star (like, getting your name registered somewhere and when a new star was discovered by astronomers it would be named after you?)... It was obviously a scam and all you'd get is a bogus certificate in the mail.
Anyway, one day someone called into the show and asked about this product that they advertised, and the host stammered a bit and basically said "well, yeah that's not true but it's all just for fun, a fun gift for people maybe". Was funny to hear him trying to justify this obvious scam because they happened to advertise with the station, even though the entire premise of the show was calling bullshit on other phony product claims.
