I like it, too! I find it very funny and it doesn't worry me that there is swearing etc. She reminds me of my mother-in-law who wasn't Irish, but walked in a similar way, and always had a tea-towel in her hand.
Whilst sobbing with laughter I am saying 'this is disgusting, why I am laughing at it'.
I think the neighbour Winnie is so good and when she and Mrs. Brown are together their dialogue is brilliant. I can just imagine my late grandmother saying some of these things, without the swearing.
