The fact that the Hooffields and McColts live on separate mountains and pelt each other with produce and hay reminded me very heavily of the VeggieTales episode “Are You my Neighbor?”. In “The Tale of Flibber-O-loo”, the towns of Flibber-O-loo and Jibberdy-lot are on separate mountains directly apart from each other. The respective inhabitants of the towns wear shoes and pots on their heads, and neither town can agree on which is better. So they’re constantly throwing shoes and pots at each other.
