weird golf rules

Watch the bizarre moment where an insect nearly cost Paul Casey a penalty shot at the Porsche European Open.

It's certainly not something you'd see very often in a bunker, but what is the ruling when something like this occurs?

It sounds unlikely but it's happened before, so make sure you know what ruling is in play if your ball deflects off a bird and goes out of bounds.

Ian Poulter almost suffered a two-shot penalty at 2004 The Players Championship over a very strange incident on the green.
