Oscar

In one episode Bette is re-doing a room and calls out for "Dave", who is never seen. In real life, Bette's personal architect/designer is named David.

Throughout the series when Bette's accompanist Oscar is playing piano it is frequently clear that is not actually playing because the position of his hands is nowhere near the actual range of what is being played.
