When Pigs Swim
The next time you say the phase "sure right I'll do that when pigs fly" think about this, they can swim. I know some pig farmers might not be surprised but I was, I had know idea pigs could swim and I certainly didn't know that there was a whole island in the Bahamas that was dedicated to it.
Exuma in the Bahamas is famous for their swimming pigs. People flock to the island for a chance to swim with the pigs. People have been criss crossing the globe to swim with Sharks, Dolphins and Whales but for the pig lover this is paradise.
