I've watched Cats since the beginning, but when Mock the Week hit it's stride a couple of years back I thought it was looking a bit stale. It's amazing how things can change.
Mock the Week has been very hit and miss over the last couple of series, while Cats has went strength to strength. Jimmy is a great host and plays the role perfectly. I've never been a huge fan of Jason's but he is what he is, safe and sometimes predictable, sometimes rather good.
I must say though I don't know if I'd still be watching after all these years without Sean Lock. I think, on this show especially, he has been consistently funny over ten series.
