Somewhere around 1964 or 1965 (I don't remember exactly). My brother, who was in the hospital (recovering from his umpteenth surgery), had a private room, but he was asked to give it up for Liza Minelli, who had just had her appendix out. Apparently her celebrity appendix rated higher than my brother's mundane colon.
Anyway, when we went to visit him that day, we didn't know he'd been moved and we walked in on Liza by mistake. She was quite understanding, and apologetic, and my (very gregarious) father stayed and chatted with her for quite a while.
One of those odd little memories from one's childhood.
