"The Glass Moan-agerie" is an episode of The Itchy & Scratchy Show.
Scratchy applies for an apprenticeship with Itchy, who runs a store selling glass sculpture. Itchy accepts the offer, and tosses Scratchy into the kiln. After Itchy blows Scratchy into a glass "NO VACANCY" sign for a motel, he sits and admires his finished work while sipping a drink with Ms. Mouse in the hot tub. When the "NO VACANCY" sign flashes three times, Scratchy shouts, "No!".
