There must be a reason for putting your best presenters on the radio on a Saturday mid-morning. There's certainly a tradition of it in the UK. Jonathan Ross on Radio 2, Adam and Joe on BBC 6 Music, Danny Baker on 5live, and for the last 4 years, Frank Skinner on Absolute Radio.
I find it hard to listen to Frank live on Saturday mornings - I like to listen to BBC Surrey's Danny Pike on my way home from being his warm-up man, so I podcast Messrs Baker and Skinner to listen to in the gym.
I don't know why Frank doesn't get more industry attention for what he is doing with his show at the moment. It is the funniest thing on the radio by a long, long way. His love of wordplay, cultural awareness, quicksilver wit, encyclopaedic memory and deadpan erudition are perfectly suited to the medium. And despite making it sound completely off the cuff (which I suspect a good 80% of it is), you can tell he's often thought about where he wants to take something.
His sidekicks are posh Emily and Northern Alun. In this clip Emily helps build up the anecdote perfectly. (If you can't see the soundcloud widget below, this link will take you to it)
