It's so rare to see two women sitting next to each other on a comedy panel show that even Sandi Toksvig seemed surprised. On QI last week Toksvig and team-mate Ronni Ancona had a witty old time sparring with Jack Dee and Alan Davies - even if the episode was called Girls and Boys and had questions all about girls and, er, boys. The show was funny, as QI usually is. Which is just the point. Women can perform brilliantly on panel shows, so why don't they appear more often? The usual one lass, three lads format is as tired patronising and boring as the older male/younger woman newsreading cliche. It's time for change.
