Sunday: We think today is the best day of the Cringe Festival at the Cavendish Arms. See Josh Widdicombe, Pat Cahill and Tim Shishodia, Cariad Lloyd, Daniel Simonsen (who was excellent supporting Simon Amstell earlier this year), Celia Pacquola, Lloyd Langford and Totally Tom. Shows starts at 3pm and are all free.

Tuesday: Do The Right Thing records the last in this podcast series at the Phoenix, with Justin Edwards, Linda Roman and Gareth Gwynn joining regulars Danielle Ward, Michael Legge and Margaret Cabourn-Smith (7.30pm, £6 / £4). We've been before and we liked it.
Two previews at the Soho Theatre: Shappi Khorsandi (7.45pm, £10) and the Pajama Men improv-ing (9.30pm, £10).

Wednesday: Shappi Khorsandi is back, this time with Tiernan Douieb and Marc Burrows, at a charity night for Action Duchenne. It's at the Adam and Eve in Mill Hill from 7.30pm, tickets £10 – to reserve email firstname.lastname@example.org.
Mark Watson's doing a preview gig at the 100 Club. At £15 it's a bit pricier than the usual work in progress show, but the cheaper night at the Pleasance on Friday has already sold out (7.30pm). Still available at the Pleasance, there's sketch group The Beta Males (8pm, £5). Or if you fancied the sound of Late Night Gimp Fight earlier in the year, they're previewing a new show at the Soho Theatre (7.45pm, £5).
Thursday: This is a cracking line-up at the 99 Club in Leicester Square: Holly Walsh, James Acaster and Pippa Evans's disturbed creation Loretta Maine (8.30pm, £9 / £12).
