1. Tourist
Don a Hawaiian shirt and some cargo pants. Add a camera, maybe a hat and some flip-flops and you're ready to go!

Ruffle your hair, and wear some wrinkled clothes. Then you can spray some water on yourself, and add some leaves from outside. To be a Sharknado Survivor, add some red food dye or toy fish.

Wear a white shirt and pants you're willing to get dirty. Then carry around some dry-erase markers. It's interactive!

If you have time, you can powder your hair and draw wrinkles on your face. Otherwise, just wear loose clothes, a fanny pack, and some sort of stick for walking.
