I've noticed then Ken has often been using an American accent. Fairytale time for example and while talking to himself in the garden.

I wonder if he is just one of those people that naturally mimic or if it is a reaction to the number of Americans in the house perhaps. It just seems a little odd.

I don't know ... but anyone who uses "American" as an insult, as he did ... is not just odd. He's a bigot.

I suspect he thinks he's being entertaining. But he's not. It's offensive.

I can't work it out. Does he think he's being entertaining? Is this the worst attempt at being the first evictee ever (as in, terribly thought out?) is he just a really unpleasant bigot? Or all three?!

I think he's just an unpleasant bigot, with a bit of thinking that's entertaining.

I could be wrong but think he might be doing a WC Fields impression - it's something I've heard other old boys of his generation do, maybe it was fashionable back in the day ?
