Wooed by a Latin lover

Nerdish Alex Horne's inventive Edinburgh shows hardly lack ambition. He has explored the science of laughter and body language and this year's affable Powerpoint presentation, When In Rome, tackled "the final taboo of stand-up", Latin. It transfers briefly to Londinium and is surely the best show ever to boast a computerised Frank Lampard.

Don't panic if you've never studied the classics. Horne, assisted by Tim Key, who frequently out-geeks him, is on a mission to revive this dead language. To this end, the performance evolves into an interactive educational joust between men and women in the audience. Good tactics win prizes, misbehaviour earns detentions.

If the format is unwieldy and frequently hard to grasp, a plethora of quickfire puns keeps things moving. Behind Horne's greysuited boffin-meets-buffoon persona, a laser-guided mind is working overtime. It takes military precision to appear this haphazard.

Soho's flat studio is not the ideal space. Clearer views of the visual gags would help, but the wordplay alone is worth the ticket price. Even if you think "sic transit" means "vomiting in a van" there is still much here to make one smirk like a veritable Nero.

Until 1 October. Information: 0870 429 6883.
