Wales

I was in a bar the other night and overheard three very hefty women talking. Their accent appeared to be Scottish, so I approached and asked, "Hello ladies, are you three lassies from Scotland?”.  One of them angrily screeched, "It's Wales, you bloody idiot, Wales!”.  So I apologized and replied, "I am sorry. Are you three whales from Scotland?”.  And that's the last thing I remember.
