One Night at the Bar,,

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

Thanks John
