as an ongoing gag of the show, one of the pair appears to be able to tell when the other has entered the room, and says their name, before turning round to see them (notably, in the episode "two faced dick", in which dick and sally swap bodies, dick enters the room and don still thinks it is sally, before turning round to find himself shocked). another of the pair's running gags is that the conversations held between them are somewhat dramatic, and reminiscent of an old film noir 1930s crime drama.
