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. Unfortunately, Peggy finds out that the dealer presents her to the public as an uneducated hillbilly. Meanwhile, Dale starts wearing a suit of armor and uses his newfound invincibility to insult people without consequences.
