9 Ceci N'Est Pas Une King of the Hill

When Hank asks Peggy to design an art piece for Strickland Propane, she creates the "Probot," a statue made out of propane tanks. Her sculpture is rejected by the city board, but picked up by an art dealer from Dallas -- who makes her out to be an uneducated hillbilly. Meanwhile, Dale starts wearing a suit of armor and uses his newfound invincibility to insult people without consequence – until Bill creates his own suit of armor and challenges him to a fight. The episode won an Annie Award for writing.[6]
