MOST fishermen are guilty of the odd photobrag, but none can match this bloke's cockiness.
The Victorian fisherman celebrated catching a huge shark by climbing inside the gutted fish, poking his arm through its gills and posing for a joke shot with his knife buried between its eyes.

The photograph reminds me of this famous cartoon image, which has been redrawn and repeated in many different sources - I've no idea where it originated. At any rate, I bet his mates bought him a few beers on the strength of the picture!
