I'm sorry about this.
I appreciate he's some kind of national treasure and everything and he does come out with the odd slightly humorous remark but it's the accent.
I worked and lived in Liverpool for more than ten years. I've spent an awful lot of time there, I'm married to a scouser, I know a huge amount of liverpudlians, obviously I'm related to plenty....
And yet...I have never, ever, ever, ever heard an accent like that. It's massively annoying. It's got to be completely made up but I just don't get it.
STOP IT! Thanks.
