Everyone has heard the expression "when pigs fly", but how about when pigs dive?

A Chinese farmer has trained his hogs to do just that. The farmer says that he originally trained the pigs to dive off of the 9 foot platform as way to keep them "happy and active".

The farmer, Huang Demin, has started a national trend, with other farmers following suit. Even theme parks have gotten in on the training of diving pigs as a tourist attraction.

Watch this video from 2012 that started this strange Chinese trend!
