Remember the episode where Homer pledges $10,000 to PBS to stop the pledge drives, and bring the show he was watching back on? (I think it was a British sitcom).
Obviously Homer can't afford to pay, but a lot of PBS characters come to the door, demanding he cough up the dough. Homer runs down the street, and is pursued by Elmo, Oscar, Mr. Rogers, Big Bird and the Teletubbies, among others.
Mr. Rogers: It's a beautiful day...to kick your a**!
Oscar: Give us the money!
Elmo: Elmo knows where you live!
