I haven't seen it but that's because I gave up with TV several years ago. British TV was always regarded as the best in the world but it's just degenerated into utter trash now. It's dumbed down, politically correct, socially engineered, offensive and quite obviously aimed at those with limited intellects and attention spans of just a few seconds.
We do have a TV but I only watch a large selection of DVDs I've amassed. Lots of natural history and classic films (and not one with a four-letter word in as they go straight in the bin! Ever hear the greats such as John Wayne use the F-word?)
I'm sure You Cannot Be Serious is as PC, socially engineered and dumbed down as the rest of the prole-feed churned out today.
