I think he's going to have to watch the kind of humour that probably give raptuous sniggers and gasps of shock with uncomfortable titters of laughter during a stage show, but the kind of humour, knee-jerk off the cuff jokes he's now used on CBB, because it doesn't wash on TV audiences on BB
Jim was joking of course, but it may well be as a result of being relaxed enough in the house and with his target of the joke, Casey - and there surrounded by cameras, so Jim's not naive - I think he just probably thought it was another one-liner and was ok to say
I don't think he was intentionally meaning to come across as 'sleazy', as I think it's just Jim's humour, and pales into signifcance somewhat compared to some of the stuff that's been said and done on this year's CBB - BUT he has to be careful not to cross what i'd call a line , again - Casey laughed, and took it as it was meant , a joke, but even so, it was crossing a line.
I think it can cause a bit of an over-reaction, and has, but it is Jim Davidson,, not Lionel, and if Dappy or Lee had said it, I don't think they'd have been as much of a fuss made. I wouldn't be surprised is his comments to Casey are raised on BBOTS, and should be really, let's just wait and see - or if BB call him up for it,but unless Casey took offence, I doubt it.
In any other environment, and to another HM, such as Liz or Lind he wouldn't have said such things, he knew Casey would laugh and that was the point wasn't it - to make her laugh and lighten the mood.
