Oscar buys every cleaning item at Hooper's Store Sesame Street : Season 9 Episode 78

"Poverty H". Ernie and Bert - Bert complains when a big letter H appears on the TV screen, so Ernie turns off the set, unplugs it, and takes a bunch of H objects out of the TV (including a hat, a house and a hamster). When he plugs it back in, a big letter I appears on the screen. Ernie wants to try fixing the TV again, but Bert tells him not to -- this is a great show. H is for horseshoe.
