Expected to be one of the big hits of the fringe, this show - created by Spanish comedy company Yllana but performed here by a British cast - turns out to be piss poor. No other term will do for a piece so fixated on the penis and what comes out of it.
We are with the inmates of an American prison, who have pretty much one thing on their minds - sex. Performed almost completely without words but with plenty of grunts and groans, this show may be intending to send up aggressive male sexuality but, with its finale in which the cast leap about naked with foot-long phalluses, appears to celebrate it. This is not shocking or funny, merely tedious - like watching toddlers play with their willies.
More disturbingly, the show tries to get the audience to enjoy the sexual debasement of women. In an ineptly handled piece of audience participation, a nervous young woman was lured on stage and humiliated. The audience laughed uproariously at this, but you wonder what they might think about it the next day when stone-cold sober. Only for the drunk or dim.
