Ahoy, matey! It's time for another Throwback Thursday. Shiver me timbers! Did you know that once a upon a time The Thundermans' Jack Griffo was the swarthiest sea dog to ever sail the seven seas? Well, he looks more like a sea puppy in this pic. But still! We're sad Cap'n Jack has given up his swashbuckling ways, but at least he doesn't have to swab the poop deck anymore!
