I always find humour in accents and the way different words are used for things up and down the country. My northern friends take the mick out of how I speak, as I do them.
I've never seen something like this written before on a news report or whatever. I actually find it really interesting and some of the bits people have posted do sound funny as they're obviously said in a way we're not familiar with. Nothing derogatory about that, not from me anyway.
