What's the weirdest item you've ever retrieved from a porta potty?

Nine years driving a vacuum truck, and I've seen things. A full set of dentures in a standard unit at a county fair. A wedding ring in a deluxe unit at a corporate picnic. Last week, I pumped an ADA-compliant unit on a construction site and pulled out a brand-new, still-in-the-box smartphone. How does that even happen? The holding tank is not a lost and found. What's the weirdest item you've ever retrieved from a porta potty? Any truly bizarre finds out there?
