Romanian comedian Radu Isac wears his misanthropy on his sleeve, and he’s here to share a few tips for like-minded individuals. In comedy, he says, he likes to find “the line” and wryly observes the level of scrutiny directed at comics’ remarks as opposed to, say, politicians. The structure doesn’t quite sustain throughout, leading to some rambling and, for someone who has set himself up as edgy, he does caveat frequently with various forms of ‘I don’t want to offend’. There are plenty of good gags though, including a yoga/holocaust-denial crossover line which is still making me giggle (honestly, it’s fine – yoga was definitely the target). Come to think of it, maybe there was a bit of an edge…

Just the Tonic at the Grassmarket Centre, until 25 Aug.
