Psychobitches

This week's sketches feature Jack Whitehall as a disgruntled Maria von Trapp, Frances Barber as two-faced sideshow hermaphrodite Josephine Joseph and Katy Brand as dancing tour de force Isadora Duncan.

Dustin Demri-Burns is as an orgasmic Nora Ephron (the writer of the film When Harry Met Sally).

Also, Michelle Gomez plays an owl-loving Florence Nightingale, Doon Mackichan stars as a hair-obsessed Delilah and Selina Griffiths portrays women's rights campaigner Marie Stopes, who is determined to educate men "whose idea of birth control is to use his wife's back duct as a receptacle for his conceptual juices", before Miranda Richardson takes us on a fantastical adventure as Enid Blyton.

As ever, Rebecca Front plays the therapist trying to get to the bottom of their disturbing yet hilarious neuroses.
