You remind me of the scene from "The Graduate" where everyone is trying to tell Dustin Hoffman what to do with his life and someone says "Plastics. That's where the future lies." (Or something along those lines.) If I recall correctly, that bit was used (much, much later) in a commercial for plastics. I didn't know until later, from an older acquaintance commenting on it, that the scene was humorous and the suggestion of "Plastics" was viewed as a rather ridiculous thing to include at the time the film came out.
