Ah, summer. A time for swimming, sunning, learning and playing — and for dads, granddads, uncles and friends, a time for teaching little kids how to fish.

Fishing can be thoroughly enjoyable and satisfying, especially when growing boys reel in the big one.

Except when things don’t go according to plan.

In this shocking video, posted to YouTube and going viral, check out what happens to an intrepid young sportsman who thinks he’s snagged the catch of his life.

As a piece in Fox News noted of the incident, “A boy named Connor has hooked a large redfish, and at first, everything seems to be going to plan. But then the man standing next to him says, ‘He’s right here.’ Then the cameraman repeats, ‘He’s right here!’ And the men were not referring to the redfish.”

The video was posted to Facebook earlier this year by Bass Masters and Fish Experts. The 11-year-old boy was fishing off a dock on Johns Island, South Carolina, with his dad.

Eventually, as the giant creature swims away with the boy’s hard-won catch, one of the men on the dock tells the young kid with dramatic understatement, “Dude, you need to cut your line.”
