NeeNee and Tito look like mad scientists with their "beanie copter hats", striped socks, lab coats and thick glasses. Oh, and don't forget to check out those high top tennis shoes too. From the toothpick to the Model T, the two silly sisters compete to see who has the best invention...showing pictures and props for many amazing inventions. And when they get to the invention of penicillin, Tito chases NeeNee around with a BIG needle trying to give her an injection! Their hilarious antics teach and delight students of all ages. Later Tito will pose  as Professor Titolino and take students on an "invention walk"
