It was a different time.
Every generation looks back on the previous ones and laughs at the dumb things people thought and did. Maybe in 50 years, our grandchildren will see our commercials and say, "How could they not have known that Snuggies were slowly poisoning us??"

Let's just say their responses to the ads are more thoughtful than you might've expected.
