I was watching Grren Acres this morning and was telling my wife about how they would cross over Petticoat Junction with Green Acres. I tried to find some clips on Youtube. Instead I found this punk rock parody of the PJ theme song, done with dolls/action figures. No megos, but I thought it was pretty funny anyway.
