There are many forms of comedy – stand-up, sketch and improv among them – and now Alex Horne has introduced a new genre as he constructs his set during the hour he spends on stage. It's a kind of Heath Robinson or Rube Goldberg device (that is, a machine that performs a simple task in an unnecessarily complicated way), and the anticipation builds as we see it coming together, and finally learn its purpose.

Panti Bliss is not a name on many people's lips outside Ireland, but over the past year she has gone from little-known club performer to self-described “accidental activist”, and this utterly charming, funny and touching show tells her story.

Normally comedy critics tell people not to sit in the front row, lest they're picked on by a particularly boorish comic. No such problem for audiences at James Freedman's interesting and unusual show about the art of pickpocketing and more modern crimes; nobody is safe from being volunteered and, in the evening's memorable finale, the subject wasn't actually in the audience when one of Freedman's tricks made him the star of the show.

Al Murray is celebrating 20 years as his brilliant invention the Pub Landlord, an autodidact, xenophobic sexist with misogynistic undertones. Who better then, you may think, to run for a certain political party in the forthcoming election? You'd be wrong, because the Pub Landlord has founded the FUKP (the Free United Kingdom Party) and he, its sole candidate, is standing for the Thanet South constituency, where Nigel Farage of Ukip just happens to be running. 

Ventriloquist Nina Conti, along with her wisecracking sidekick Monkey, has emerged as one of the sharper comedy acts of the past few years but Nina Conti Clowning Around was an uneasy, far from comic film. Embarking on a new direction, away from “entertaining drunk adults” as Monkey put it so winningly, Conti set herself to trying to entertain sick children as a hospital clown, or “giggle doctor” to give them their title at the Theodora Children’s Charity which was her starting point.

Well, here’s an interesting endeavour. The 2,000 Year Old Man was a series of improvised sketches performed in the 1960s by Mel Brooks and Carl Reiner. Brooks played the old guy, talking about all the great names in history – Jesus, Joan of Arc, Napoleon and many more – he has known in his long and eventful life. Reiner was the straight man, lobbing the questions that Brooks would then riff on. What started as two comedy mates having a laugh become television sketches and five albums-worth of recorded material.

Nick Mohammed's show has had a slight change of title since it debuted at the Edinburgh Fringe last year, where it was called Mr Swallow - the Musical, and garnered warm reviews for its shambolic silliness.

The Soho Theatre's lawyer was in the night I saw Kim Noble's new show, and that's no surprise as it pushes a few boundaries – public decency and legality being just two. In many ways it's typical of Noble's output as it plays with the audience's perception of real and imagined events, blurs ethical lines and dares us to be offended. As we walk in, for instance, he's Googling things such as “weird cunt cum” and “dwarf sticking milk bottle up arse”, and later we see footage of him defecating in a church – “It was a Catholic church so it doesn't count.”

Due to unfortunate circumstances I am unable to give a star rating to this show; 15 minutes into the second half a cast member collapsed on stage and the performance was cancelled. At the time of posting Ted Robbins (extreme right in the picture below) was recovering in hospital, in a stable condition, and we wish him a speedy recovery.

It's always an education to see a comic – now a part of the British comedy establishment – performing a gig in his own backyard. And Dara Ó Bríain, at the Royal Theatre in Castlebar, Co Mayo, was just that; he had, as ever, done his homework, immediately throwing in several local references, plus a few more that his Twitter followers would recognise, and told them that returning to his home country on the Irish leg of his Crowd Tickler tour after a few years away from the stage was an education for him too.
