I've been known as Sharkey since 1960, thanks to a twisted junior high mind and a good friend. There is a pizza place in Port Colborne, Ontario of the same name, but alas they have no shirts. Also have 3 other shark shirts. One son has 2 real sharks in an aquarium, but one dog is enough wildlife for me to care for right now. They are 40 feet long and weigh 13 tons.
Divers can hitch rides on their backs since they are extremely docile and eat plankton.
That's like being able to zero in on one red pixel in about 4 solid white computer screens.
