When I was out at Union College in Schenectady N.Y, we had a great college radio station that would give away pizzas, movie passes, clothes, etc. for answering trivia questions throughout the day. One day, my friend and I recorded a trivia question on our tape deck and kept the tape in the deck. A little later one of our good friends came over to visit and we were all listening to the campus station. As soon as one of the songs ended, we turned on the tape with out our friend noticeing and the D.J asked a trivia question for a large pizza. Our friend knew the answer and since he was closed to the phone, he immediatly picked it up and dialed the station. He was really excited that he got through and started yelling the answer at the mystified D.J. He was incredibly embarrased, we were trying so hard not to laugh it hurt.
