1. A big blue metal star
2. A vibrating toothbrush that a girl swore she “swallowed” all the way down to her lower large intestine
3. A button
4. A tooth
5. A tampon
6. Many, many, many toys without wide bases
7. (Bonus) An old man with a big tattoo of a smiley face on his butt

Those are just off the top of my head. It was always great when my eyes would focus on a procedure photo and start to wonder “what the hell is that?”
