One of the most enjoyable parts of broadcasting school was getting to write commercials. Because most of the commercials a student wrote wouldn't air on any radio station, you could prove you knew how to write ad copy while sometimes incorporating your sense of humor into it.
In a commercial I wrote, I asked, "Want to clean those gutters without climbing a ladder? Let (company such-and-such) clean the gutters for you. At (company such-and-such), they'll take the risk of falling and killing themselves for you..."
My tongue-in-cheek commercial elicited some laughs from instructors and students, although one instructor cautioned me, "I take it you know that you could never actually air this commercial. Obviously, you don't want the audience to say, 'Oh, my God,' while imagining the poor gutter workers falling off the ladders."
Well, yes...I knew that. Invoking the image of workers falling off ladders isn't exactly humane--or good for business.
