Rob Delaney

Officially the 'funniest person on Twitter', Delaney's Soho Theatre run last year sold out in an hour, after just one tweet from the man himself. Now this acerbic American stand-up is back in London playing the much bigger Shepherd's Bush Empire. Delaney has only been a professional comic for a few years years, but his profile has rocketed thanks to his hugely funny (and award-winning) Twitter account: @RobDelaney. As a stand-up, he has a sharp, bitingly funny wit.
