OK, here's the scenario. Your partner casts out over a tree and hooks a bass. it swims under the tree, past some branches and gets stuck on the surface. He can't pull it in and you can't reach it with the boat or the net.

The fish is on the surface with it's mouth open. You cast your lure in to the fish's mouth and hook it. He lets his line slack and you reel the fish in.

Can you keep it? :)
