Hi Rob
The fish has a man in a wet-suit attached to its face by a hook. The man in the wet-suit is whooping and laughing, being dragged around the river with little or no chance of landing the fish (and it seemed like he had no intention of landing fish.) That seemed to wind the Canadian up.
I saw the tenkara fisher (I seem to recall there's another name for this form of extreme fishing btw) dragged downstream through two pools before losing the salmon. Actually I saw him do that several times while his fishing partner filmed the action from the bank, catching the episode on tape seemed to be the point. It struck me I was watching something that could appear on Jackass.
(Incidentally, Webster includes Salmon fishing in The Angler and the Loop Rod, but the tackle for salmon is not a Loop Rod - he suggests a reel with 60 to 100 yards of line.)
