Pushing the concepts of bizarre and inventive out past the stratosphere, Luke and Harry are bringing their 2013 Edinburgh Fringe hit back to London. Combining disturbing shadow puppetry with gameshows and, er, ritual sacrifice, it's a voyage of discovery for all involved. This is true experimental comedy, probably one of the stranger things you'll ever see, but if you love a bit of space adventure (or some interspecies action), you need to check this out. General admission. Over 16s only.
