Dr Sketchy's is the brainchild of Molly Crabapple, who started the franchise in New York. The ethos behind it is that not everyone is a perfect artist, so the emphasis is not on the technical proficiency of the art drawn during the show, but the wit behind it. Sketchy's is a weird and rather beautiful marriage of burlesque performance and life drawing class, with prizes for the best sketch often given to the funniest, rather than prettiest, picture.

Model Dolly Tartan opened the show as Wonder Woman. When one of our audience members started shrieking at the back of the room, menaced by a threatening villain, Wonder Woman dashed to her aid, lashing the culprit with her Lasso of Truth and dragging him up on stage. To add to his woes, she then proceeded to pose with him while the audience sketched, only letting him go when he was sufficiently chastened. A long pose allowed the artists time to draw a front page for a Wonder Woman Comic, for which we couldn't choose just one winner, instead awarding prizes to three fantastic covers.

The second half of the show saw the return of Dolly Tartan as Judge Dredd - Judge Dredd in a strict pencil skirt, stripping down to 'Leave Your Hat On.' Naturally, Dredd kept the helmet on the whole time, even when stripped down to black pasties.

It was deliciously surreal, and the act was followed up by four short poses, which allowed the audience to draw four panels of a one page comic. There were some extraordinarily proficient artists in the room, but the final prize went to a comic with brilliant artwork and the cleverest story.

If you want to flex your drawing skills with a fun and informal setting, this is the way to do it. The theme varies every time, which means, sadly, that you have indeed missed Judge Dredd stripping. The good news is that the next theme will be just as weird and undoubtedly wonderful.
