Last night's 10 O' Clock Live confirmed it, with the former prep school wank sock spluttering his way through a series of horrendous interviews.
Leading TV reviewer and friend of all beasts AA Gill says Mitchell is not the first star to suffer this way. He said: 'Dara O Briain is still technically funny but just looks sinister these days. And who can honestly say they didn't think Frank Skinner had got the Aids a few years back?'
Mitchell's agent Robert Meringue led the tributes, saying: 'I'm gutted. He was the Micky Quinn of satire, and now he's gone.'
Comedy partner Robert Webb added: 'I'm devastated. David fell up the stairs last week while carrying a tea tray and I thought for a second "he's back". But last nights show finished him off.'
Micky Quinn was unavailable for comment.
