Don't you remember the notorious Don Martin cliffside romance strip?
(John and Marcia agree to jump off the cliff together but she gets cold feet at the last second and he jumps by himself. Now it just so-happens that there's a trampoline at the base of the cliff. John hits the trampoline and is bounced back up. He cries, "Marcia!" and she replies, "John!". This goes on for several ups-and-downs, and finally he asks, "Marry me, Marcia!". She answers, "No, John!". Meanwhile, two truckers remove the trampoline. Splat!)
