There is brave, there is crazy...and then there is this.

South African real estate agent Grant Campbell got a shock that left him scratching his eyes this week when he found a very quirky fisherman a couple of kilometres from shore.

The man's "boat" was an inflatable rubber tyre and his "motor" was a pair of fluorescent flippers. Clad in shorts and a T-shirt, he was dangling a line over the side of his craft.

"2km out to sea I see this man fishing for dinner, I couldn't believe it ...Tractor tyre and a pair of flippers, I had to give him some of our fishes for his hard work !!!," Mr Campbell said in a Facebook post that has since been shared more than 1200 times.
