Green Acres S03E15 - No Trespassing

Oliver's crabby attitude leads everyone think he's about to snap from overwork. To help him relax, Lisa takes him on a picnic by the lake. That's where he runs into gun-totin' Ira Hatch, who hassles him about trespassing on his property. When he tells the locals about the old man, they declare Haney the winner of the "Oliver Douglas crack-up pool" because Ira had died 20 years earlier.
