Tbh, I saw the trailer for this and thought I'd give it a wide birth. But a mate of mine said it was ace, total puerile toilet humour mind, but if you go with it, it's very funny.
I'm so glad I went, I've not laughed so much for years. Some bits went too far it's true, but loads of scenes had me weeping with laughter. Perhaps this may become the 'guilty secret' kind of film, but I think it was hilarious.
