A snake sighting is usually not a laughing matter, unless it's part of a father's prank on his adult son during a family outing.
In a video posted to YouTube, the unsuspecting son is caught on camera looking through a pair of binoculars at a lakefront when his mischievous father decides to make their trip outdoors a little more entertaining.
The action gets going at about 1:24 into the video, when the father quietly drops a fake snake near his son's feet as they stand on a dock.
The result of which is a grown son on the run, and a family laughing out loud at their outdoor shenanigans.
