That was the road paving episode. Oliver had complained that a long forgotten allocation for roadwork be acted upon by the State. As it turned out part of the allocation was to go for straightening the road which required the demolition of the Ziffel residence which had been purchased by the State years earlier. Doris was blocking the bulldozer from tearing the house down, Oliver was surprised to see her on the ground. You might recall the bulldozer was going to back up to go around Doris but Lisa was now on the ground behind it, Fred immediately cautioned her to up she might get hurt.
Yeah it was likely because she was laying in front of the dozer, but the way he was looking at her I kept thinking... "Is he gonna say something about her appearance?!" lol
so weird that just last Friday I noticed that Mrs Ziffel had a wardrobe malfunction -- her bra must have twisted and her left breast was kinda in the middle of her chest and the the right one was mostly under her right upper arm
