And this is what you DON'T do...

Face Palm:

Police: Gun safety lesson goes awry when dad accidentally shoots son. 
  
There isn't much to the story.  Sounds like the son is all grown up, and him and dad where comparing each other's pieces, and showing each other how to unload them.  Dad went to prove his was unloaded by pulling the trigger.  Luckily, instead of seriously injuring his son, they got to reenact the 'Something jumped up and bit me' scene from Forest Gump.

Sigh.
