The To Do Tattoo is so funny, and yet such a good idea for those of us who are getting forgetful in our old age. It's a to do list tattoo for your hand, or other body part, and a skin-safe marking pen, with which to write your list. This is perfect for me, since as soon as I write my to do list, I promptly lose it! It's also perfect for husbands who conveniently "forget" to do things, and also for teenagers. I love it!
