I recall a particularly strange episode of "Moonlighting" a few years ago where a chase scene broke through the fourth wall, just like in the finale of "Blazing Saddles." Also, I saw a recent rerun of "Green Acres" where some of the opening credits (director, writer) were written on chicken eggs which Lisa inspected and commented on in the opening scene (i.e., "Oliver, why are there credits on these eggs?"). Has anyone written anything tying this tradition together? (from George Burns to the "Simpsons" ...) Pam Inglesby University of Pennsylvania
