Lisa's convinced that Hungarian gypsies have placed a curse on her when she receives a dreaded blue feather in the mail. To "de-hexify" her, Haney sells Lisa a ridiculous recipe that she mixes up, places in a green purse, and hangs outside the front door. Eb gets a look at it and panics because the "green purse hex" will bring a drought. He counteracts it with his own concoction in a yellow purse. Oliver takes action to put a stop to all this foolishness.

For Lisa's birthday gift, Oliver plans to gets her a horse. Mr Haney delivers one, and it's not your average nag. Its name is Mr. Fred, a talking horse who's also a has-been TV star. Meanwhile, the locals decide that Lisa has a drinking habit and attempt an intervention.
