What to put in an adult pinata?

We are having a party for my sister who is turning 18. She has a one year old little boy, and is finally going to be an adult (by government standards). So as one of the things to do we are going to have a pinata. The ideas we have so far to put in the pinata are mini note pads and pens, hershey kisses, mini vodka bottles, travel size smells goods, bubble gum, quarters, and scratch off lottery tickets. Anyone have any different ideas? Keep in mind that it will be an event with family and friends so condoms, drugs, and other ideas of the sort would not be appreciated. Also if you have ideas of other things we could to at the party I would love to hear them.
