That does sound fun. I was just imagining waking up as funnyman Jack Dee, in bed with his wife. She rolls over and says "say something funny to start the day like you always do, Jack!" You've got nothing because you're not really funnyman Jack Dee, he's just a suit you're wearing. You make an excuse and go downstairs where his kids are waiting. "Say something funny like you do every morning, dad!" you say. You feel bad about letting them down but you have to tell them to fuck off because you have to work. You see a note on the fridge reading "HAVE I GOT NEWS FOR YOU RECORDING TODAY." You gulp. Maybe you can get through it, you tell yourself. You arrive at the studio and Paul Merton says "hi, Jack." You don't know how funnyman Jack Dee would respond to that so you panic and say "I have nothing to say to you, Merton. I think you know why." You're doing well during the recording, just reading the autocue, when Paul brings that incident up. You freeze awkwardly. You look to Ian Hislop for help but he just sneers and says "looks like you're less popular than ED MILIBAND today, Jack!" and pulls a funny face. You sink down into the chair, wishing you were back in your own body. But there's no going back. You're Jack Dee now. And you're terrible at it.
That's what I was imagining.
