After Rossini's opera, for many years they were named Clorinda and Thisbe, now these names have fallen out of use and their names have changed to suit the fashions of the times. Often they are named after flowers, illnesses or celebrities. Notable ugly sisters have been played by Terry Scott and Julian Orchard (Theresa and Julia), Brian Murphy and Yootha Joyce (Georgina and Mildred after their sitcom characters "George and Mildred"), real life sisters, Elsie and Doris Waters (Gert and Daisy after their radio sitcom characters),
