As well as being tragic, Dot is scripted as a comic character. Brown has discussed the humour she incorporates into her performances: "I think Dot would be awfully boring if she weren't a bit comic [...] I always thought I had to put an edge on it, an edge of comedy, which just means doing it more seriously than you would do. If you want to play comedy then you have to be very intense about it [...] very, very serious." Some of Dot's catchphrases are used for humour, such as "Ooh I say!", uttered when she is "stuck for words". In 2004, Brown discussed the origin of the saying: "It was written once in the script and I quite enjoyed it, so I used to say it occasionally when it wasn't in the scripts. It was useful because it could be said in all different ways. Dot's very straight-laced, so it helped to express her horror at what went on." Brown revealed in 2008 that she has tried to cut down the use of this, along with the mispronunciation of her employer, Mr Papadopolous, as she has become a little embarrassed by them now they are so known. Mr. Papadopolous is the owner of the launderette where Dot works. In a long-running joke, Dot has difficulty pronouncing his surname, and for much of the show's history he has been referred to as Mr. Oppodopolus, Oppydoppy, or varying other mispronunciations. Brown has said she enjoys playing the comical aspects of Dot, stating, "She's not dreadfully funny but she's amusing and I like that because it lightens it up a bit."
