I have one, my father has two, my older brother has one (that I know of) and my little brother has several…and thanks to Safety Tattoo, for only $19.95 my children will have at least 30. These things are awesome. Just tat your kid, and don’t worry if you loose track of them…some stranger is bound to look them up and down for a tattoo and call the number affixed to their skin.
What would be even better is…say your kid is out of control. Just tat them up with the In-Laws phone number, take them to the zoo, distract them at the monkey cage, and enjoy the rest of the day off.
