The laughing Buddha figure is definitely from "Park Plaza 605" a.k.a. "Norman Conquest," which has only an off-screen spanking. Perhaps you have it confused with another film.
My own "lost scene" is from what looked like a Latin American black & white crime or spy film from the 60's. A saucy young secretary is acting like a total brat around a number of visitors in the office. As soon as everyone else has left, her boss beckons to her and gestures ominously toward his office. She slinks across the room with her head hanging and a classic little-girl-about-to-be-spanked air. No actual spanking, but a nice scene.
