A bad night

I was at the bar last 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..........
