Sense of humour is definitely different the further south you go. Generally the Geordies, Scousers and Mancs are a good laugh.
I'm nae being funny but how did Scots get the reputation of being tight?

They're tighter than 2 coats of paint doon there.

Ive been in company of Scots that are tiggt. One of my good mates is tight as ****. Ive also got an English pal that is slso tight as ****. Good and bad in both. Bit harsh the Scots are tarred with that brush though.
As for sense of humour I have many cockney friends that are funny as ****
