Rather than being a school sports day pep talk, the titular egg refers to an oddly-shaped rugby ball. Archie and Ollie are proud members of the Clapham Falcons rugby team. Having roped in their reluctant mate Freddie to play a match when team numbers are down, the love triangle between Freddie, Archie and his girlfriend Ellie unfurls.

This began life as a mockumentary short film but, unfortunately, its transition to Fringe show isn't a particularly successful one. The group does excel through audience interaction, with manchild Ollie stripping off to greet the audience as we stroll in, and the recruitment of extra players from the crowd creates energy in the room.

However, a lacklustre script hands all the best dialogue to Ollie, leaving the other two wading gamely through the sub-soap plot. There's a chance it may get slicker as the month progresses, but sadly it feels like a wasted opportunity to do something a lot sharper and more akin to their much snappier film version.
