In a famous double-act, the names are ALWAYS said in a certain order, to a point where it would sound very odd the other way round. This can apply to other things that come in twos, like Egg and Cress. Who has a Cress and Egg sandwich? Named for the two popular British presenters, who have stated that they even stand on stage/set in the same order EVERY TIME to stop people from mixing them up!
