That doesn't look like a circle hook to me. I crush all my barbs down so releasing the fish is a breeze.

Poor guy had a pretty rough day!

 

 

It's not. Looks like an octopus hook. A circle hook would not have snagged the fish. 

You guys are right, octopus hook

Looks like someone's wacky rig hook. Fish probably bit the end of the worm and the hookset drove the hook right through his eyeball. Since the fish was snagged he probably ran like a freight train and broke the guy off. Pinching the barb and removing was the right thing to do. 

Two years ago I caught a nice largemouth on a shakey head with a leader and hook coming out of its "waste hole" ..lol went back one week later to the same spot with the same shakey head and caught the same bass! Thought that was pretty cool!

 

this has happened to me a few times.  I usually take a pair of needlenose and pull as much line out of the fish as I can.  better than having the fish swim around with line coming out of its butt
