I love it! What a great idea! It's groundbreaking! Well, it's new anyway. Eh, not that new, we're from the '70s. It'll never work. It's too much work! Boo! Get off the stage you crazy bear... er, dog.

(Serious comment - I do like this idea. But I think "heckling" only works on websites where people know they're playing a game. Statler and Waldorf stay in their box for a reason. A more alchemical approach might work, though, if there were a game culture of the characters being relatively respectful to the original writer.)
