Its so funny that a man practising shooting fires at a tree which in turn fires back at the man.

Using a tree for target practice sounds harmless enough, right? That wasn't the case for an Iowa man who is recovering at a hospital after the tree he aimed his gun at fired back.
No, this isn’t an April Fools’ Day prank playing on the much-maligned M. Night Shyamalan film “The Happening.”
An Iowa man is expected to survive but will have one heck of a story to tell after he fired his pistol at a tree only to have the shot ricochet and impact upon himself.
27-year-old Logan Bunn transported himself to a nearby hospital in La Crosse, Wisconsin. The Allamakee County Sheriff’s Office says the incident happened at about 4:30am on Sunday morning.
In the ongoing war between man and nature, many more trees have fallen at the feet of their human counterparts. But there have been notable exceptions. Last month, an Illinois man was killed when a tree he was attempting to cut down fell upon him.
And on Christmas Day 2012, a Houston man was killed when he was attempting to clear a fallen tree from the street outside his home. During the removal effort, a second tree fell on him, causing the fatality.
