Last time I looked the Tina Fey/Amy Poehler Meet Your Second Wife sketch had had around 300,000 views. The five-minute Saturday Night Live clip has now topped a million. It seems to have struck various chords with viewers. To me it shows how at the top of their game Fey and Poehler are at the moment. And it shows how American comedy is not afraid to go to dark places in humour, making audiences laugh and making a point too. I'm not saying UK comedy can't do it too, thanks to the likes of Sharon Horgan, Charlie Brooker and Julia Davies (where are you Chris Morris? British TV needs you), but this is real mainstream comedy, two Hollywood stars truly nailing the patriarchy. It is inspired, original and daring. And funny cos it's true. The last time I saw Tina Fey she was doing "to me, to you, to me, to you" with Josh Widdicombe on The Graham Norton Show. I have to confess that made me laugh but I felt slightly dirty afterwards. This is much more like it. Fey and Poehler should call themselves The Chuckle Sisters.
