Griffin Hellbender - What if I Was Justin Tiger Shark?

If surnames were invented today I would request that they be you choose an animal that you feel best represents you and that is how you get your last name. Imagine if instead of your brother Justin Mackeroy which we can all agree is a pretty humdrum. What if I was Justin Tiger shark? That's every day I want to live in a tiger shark fashion. Admittedly I'd have to change my first name to striking distance. Yeah but if I could get that second half I'm halfway there.
