I trimmed your leg for you! No need to thank me.
Uncle Accidentally Whacks Nephew With Weed Whacker

This is some home security cam footage of an uncle trimming the front walkway when his grown nephew comes over to hand him some gloves, and he accidentally thanks him with a string trimmer whip to the thigh. Ouch. And trust me, as someone who cuts his entire lawn by removing the guard from his weed whacker and letting out almost 2 feet of string, I know exactly how this feels. Not good. Still beats a lawnmower blade though, which is why I started cutting my yard with a weed whacker in the first place.
