I vaguely remember an advert for Heinz beans donkeys years ago, a geeky looking girl is sitting at the table complaining she didn't like beans. Her mother looked sternly at her and said something to the effect 'Margaret Roberts, eat your beans or you'll never amount to anything!' She then looked at the girl, pondered a bit and took then beans off her! Margaret Roberts was Margaret Thatcher's maiden name, it was only shown a few times and then was made to disappear suddenly.
