Before we got on the 'do not call' list I would always have some fun with the marketers that called. They would ask if they could have my info and I would just simply say 'no' in a clam voice. They would ask why and I would say 'I don't know', and they would remain silent. They would then proceed to tell me about the product they had and I would be like 'hmmm, that sounds nice'; or 'WOW! I can't believe they made something like that!'
Pretty much anything to mess with their heads. They would eventually hang up on me instead of vice versa which made it that much more fun.
If I ever get called again I'm going to pick up and say 'Hi, my name is (fake name) and I was calling you on behalf of (fake company) to offer to you this new product we have...' I was then going to list off whatever it was and see what they'd do. I can just see them saying, "Ummm sir, I called you..."
