Boothby Graffoe is on a mission to reveal to the good people of Britain what a hollow sham the National Lottery is.

Judging by this performance, he’s spreading the word pretty successfully and making people laugh at the same time.

Scratch is the second half of an evening filled with amusing facts, wry observations and off-the-cuff, unnervingly accurate improv, the source material ably provided by an appreciative audience.

By the time Graffoe got on his soapbox about Camelot, we would have happily listened to anything he had to say.

Graffoe is as funny now, and twice as likeable, as he was when I first saw him 19 years ago. And as he unashamedly pointed out, he retains some of his best jokes from his past years of stand-up.

Lines such as, “I have two beautiful children. And three hideous ones,” delivered in his trademark throwaway drawl had the audience chuckling before he’d even delivered the cutting punchline.

Twenty-five years of stand-up haven’t blunted the tools of this immensely likeable, musical, storytelling comedian. And you will probably rethink lining the pockets of Camelot after this show.
