A night at the pub

View_From_Here sent us this hilarious joke:

I was at the pub 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.
