Anyone would be surprised if they hauled up a fish this size, but Jon Black's reaction is absolutely priceless.
He gets more and more excited as he reels the giant goliath grouper in, to the point where he's practically screaming in ecstasy. Even when the beast breaks his rod!
The fish, which was over two metres long and measured 185 centimetres around, was caught in Sanibel Florida.
According to the filmer, it weighs an estimated 522 pounds (236kg) - about the same as a Shetland pony!
