This brings a whole new meaning to the phrase 'toilet humour': comedy gigs in venues that used to be public bogs, to raise money for and awareness of the fact that 2.5 billion people across the world don't have access to a loo.
Water Aid is arranging a mini festival of pant-wetting laughs, ending on World Toilet Day (that's really a thing) on 19 November. Choose between two nights at ArtsLav in Kennington, featuring Bec Hill, Phil Wang, Helen Lederer, Tom Craine (also to be found in Jigsaw) and Mark Cooper-Jones (of WitTank) among others, a comedy night-slash-disco in Hackney's Convenience, or test your own skill at making jokes float with a comedy workshop at The Attendant, Fitzrovia.
Tickets cost a bit more than a penny — £15 plus booking fee, to be exact — but the profits go to help Water Aid's work with sanitation. They reached 2.9 million people with lavs last year, not only saving lives (diarrhoea kills 760,000 children under five each year. Puts Ebola into perspective, doesn't it?) but boosting local economies.
Or if it's just hanging out in toilets that makes you happy, see our list of some of London's other bars and restaurants in former crappers.
It's No Joke comedy festival runs 16-19 November at various venues around London. Tickets cost £15 + bf. For more information see the Water Aid website.
