There are a fair few stand-up shows these days which make the promise of teaching you about X or busting the many myths on Y and Aidan Bishop's show Misspelled is no different. In true training day style Bishop starts us off with a video interviewing the ever knowledgeable British public on what they know about dyslexia (turns out, not much) and then launches straight on into a PowerPoint presentation. Only, Bishop isn’t like the others. Whilst other comedians mostly use these gimmicks as scarcely veiled devices to talk about just about anything else, Bishop shows genuine concern over his topic, wanting us to leave knowing a little but more about what it's like to have dyslexia.But before I start making this sound like a dyslexic support group, be assured that Bishop certainly has no qualms in finding humour in his handicap. As we are led through his early childhood in his softly spoken Queens accent, we are introduced to his mother. I'm sure that Bishop had much grief with this woman over the years but it must have been worth it for the cracking gags she supplied.As his story moved into the present as a diagnosed dyslexic, Bishop showed us the various devices that help him in his day to day life: first playing an example of a particularly comical audio book he found himself reading along to one day and then introducing us to the talking computer he uses to write his scripts, which it turns out is very good at stand-up itself and is also pretty dirty.Bishop has been on the comedy circuit for a while now and this is clear in his perfect delivery and comic timing. Even when a woman in the audience revealed herself to be a dyslexic specialist Bishop stayed the true professional not letting this faze him a bit, joking 'Oh God, I've just been making all this crap up.'Occasionally political, sometimes a bit dirty, whatever it is, Bishop has got this comedy business down to a tee.
