I think that actress was famous enough to be known by her initials. Perhaps too long ago, but giving it a try.
Nowadays she would be an actor. Doesn't work so well in the bishop jokes.
The BMW Isetta "bubble car" had a door that opened at the front and no reverse gear, so if the unfortunate driver parked too close to a wall, he had to wait until some kind sould pushed him back to allow him to get out.
