TV's TV

There have been plays about plays, books about books and movies about movies, but it's rare that there's television (fictional television, that is) in which people watch TV. Here are some shows I've managed to think of:

• Invitation To Love, a soap series featured on cult classic 'Twin Peaks'.
• Krusty The Clown featuring The Itchy and Scratchy Show, ultraviolent cartoons wrapped inside the antics of a worn-out clown, as featured in 'The Simpsons'.
• Eye on Springfield, the hard-hitting news show from the same series.
• Sick, Sad World, a TV show showcasing bizarre happenings, enjoyed by 'Daria'.
