In almost any Zucker film, you'll see a certain woman. She has small parts, but she's usually there. It's their mother. For example, in the movie "Airplane", the woman having trouble putting on her makeup is her. In the 2nd "Naked Gun" movie, she is sitting at a patio table, talking with a couple of women. She says, "He gets around very well in the wheelchair", reffering to the scientist, who happens to fly by in front of the moon, with a nod to "E.T."
