Anyone who has dipped their toes in the choppy waters of internet dating will find this sparky, well-observed two-hander from Australia's Out Cast Theatre enjoyably close-to-the-knuckle. Butt Boy (Jamie) and Tigger (Matt) meet in a chatroom late one night. After a round of coy flirtation, the pair proceed to act out a series of intricate sexual scenarios. But, having shared their most intimate fantasies in cyberspace, will the pair actually hit it off when they meet in the real world?

In the scenarios these late-night chat addicts enact online, playwright Steven Dawson has fun sending up the corny sexual fantasies beloved of bog standard gay men's porn (encounters in the gym showers, the army barracks, tussles in hay bales with stable boys), while poking fun at the gay male's fabled horror of intimacy (intriguingly, an audible rumble of disquiet went around the room when one of the characters mentioned the 'L' word). The sedentary nature of online interaction is counteracted by the punchy dialogue, which drives the action, and there are engaging, energetic performances from Felix Allsop and Angus Brown.

If the script descends into exposition towards the end, and the soundtrack is occasionally a little on the literal side, these are minor complaints about an otherwise polished, funny and moving slice of late-night entertainment.
