This is the one; the best Carry On in the entire series; it's an absolute gem from beginning to end. Convenience was unpopular at the time, due to it's negative portrayal of trade unions, but looking beyond the surface, there's a wonderfully rich story which is not just full of jokes, but also full of good humour. My favourite segment is the outing to Brighton; the gang are all out to have a good time, and they certainly succeed in that. Put this in the video, sit back, and be prepared for one of the funniest films ever.
