A ‘set list’ contains written words that comedians use to remind them of which jokes they will do. But what if someone else wrote them an outrageous set list and they had to create comedy on the spot? Top comedians are given original and deranged topics with literally zero seconds to prepare, performing seamlessly as if it’s the act they normally do. See the mental wheels turning in this playground for the comedy mind. Now a series on Sky Atlantic TV (UK) and The Nerdist Channel.
