Borrowed from a FB Friend...
I was in a pub on Saturday night. Had a few drinks........
I noticed two large women by the bar.
...
They both had strong accents so I asked "Hey, are you two ladies from Scotland?"
One of them screamed "It's WALES you friggin' IDIOT!"
So, I immediately apologized and said "Sorry, are you two whales from Scotland?"
That's all I remember...
