Sean Morley's opening 'joke' is worth the admission price alone. It's a sprawling, high-concept fantasy featuring a prank-loving king, several demons and an essential element of audience participation. Morley is present in real life and through pre-recorded voiceover, where he lends his lyrical skills to describing the landscape ('hench mountains, fit little lakes', which recalls Tim Key's poetry). He has the audience completely keeled over as the scene – somewhere between The Mighty Boosh and Tolkien – plays itself out.

What follows is equally unpredictable, with the comic reinventing himself as a mischievous talk-show host interrogating audience members with the big questions of our time. In the hands of a lesser comedian, this bit would have the potential to collapse but Morley directs the section with intellect and wit; he's not just doing it to pass time or to cover up a lack of preparation.

Soon I Will Be Dead and My Bones Will Be Free to Wreak Havoc Upon the Earth Once More is a delightfully ambitious, endlessly creative hour of lo-fi comedy, which covers fear, self-acceptance and trust. Find what you need to find, but prepare to laugh very hard indeed.

Heroes @ The Hive, until 25 Aug (not 21), 3.20pm, £5 in advance or donations at the venue.
