02 - Samantha Jones (Sex & The City)
03 - Bree Van De Kamp (Desperate Housewives)
04 - Lynette Scavo (Desperate Housewives)
05 - Carrie Bradshaw (Sex & The City)
06 - Miranda Hobbes (Sex & The City)
07 - Susan Meyer (Desperate Housewives)
08 - Edie Britt (Desperate Housewives)
09 - Gabrielle Solis (Desperate Housewives)
10 - Mary Alice Young (Desperate Housewives) You're dead, hun!
