I was in a pub last night and saw two “girls of size” (as Political Correctness now requires us to say) by the bar.
They both spoke with a very strong brogue accent, and making assumptions about their origins I said,

"Hello, are you two girls from Scotland ??"
... ... One of them screamed, "It’s WALES you f***ing idiot !!"
So I immediately apologized and said........

“Sorry, are you two whales from Scotland ??”
