Another misunderstanding

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