Duckman: Private Dick/Family Man S03E07 - Apocalypse Not

After the city gets attacked by one of Duckmans over-inflated dolls, the city decides to have an emergency drill where all the residents go underground till the drill passes. Duckman fails to know about the drill and has a city-wide 'party' (involving mass destruction) while all the residents are gone. Eventually the residents return to chase Duckman out of town.
