“Dead body. It was an apparent OD. Booze and drugs. Also a nitrous tank. (That night after work was fun).” –Simplekin77

My dad used to be the guy in charge of renting out the Knights of Columbus hall. Per policy, he had to be on-site during the event, but would clean up after. The cleanup would usually be the next day, and I’d come along to help. The best thing we found was a $500 tip left behind by the father of the bride after a wedding reception with a little thank-you note. The worst was finding the punch bowl the next day after someone had puked in it and put a lid over it. I’m pretty sure it had been spiked with something pretty strong before that, too.” –Lentra888

“I was told to cut everything off of the “The Tree of Happiness” where everyone was told to write something down that made them happy, and tie it to the tree. It was in a public park, so they all had to be removed, and I put them in to a jar because I didn’t think I should just throw them away. So now I still have what I call the Jar of Happiness. Still don’t know what to do with it.” –Abacae

“Not quite what was asked but I have an uncle who runs a 2 day festival. It is held on tribal land at the end people from the tribe were ready to clean up after the weekend festivities that was part of the contract. After last act he gets up on stage and asks the festival goers to help clean up after themselves. The crowd left it clean. No clean up needed after. So guess clean grounds after a weekend festival may count.” fhfuudjdfhh

“Worst is definitely a tie between the 5 liter water carrier filled with urine, or the lidded saucepan containing a single, fairly large, poo.” –ginebriated

“I worked as a sound engineer for an under-21 club in Alaska for a couple years. You’d find all sorts of stuff left behind after shows. For some reason nearly every other show some scene kid would decide to plug their phone in to charge somewhere and forget about it. We’d also find all sorts of drugs, mostly weed or pills like adderall or vicodin, but also oftentimes half-empty bottles of shitty booze (very often pints of monarch vodka or R&R whiskey), whip-it canisters, 4Lokos (this was during the original formula years), and empty bottles of Robotussin Max Cough (back in the days when it was all DXM). I think the best thing we ever found, though, was a Mesa Boogie Triple Rectifier (a $2500 amp that was probably going for $1700 new at the time). Me, the promoter, and my guitarist called literally every guitarist that had played there that week to try to get it back to them. None of them claimed it. So my guitarist got a new amp out of the deal.” –gothdaddi

“Collected tents and sleeping bags for a homeless charity, also picked up hundreds of cans of beer and cider. Put the cans in a bath at home in sterilizer fluid, then sold them cheap at a party as a fundraiser for the charity.” –miffyonabike

“I was a volunteer at a large festival, though I didn’t work cleaning the camping area. But I did speak to one of the scavengers who roamed the camping area afterwards. He said the best loot was car batteries and Euro pallets. Turns out there are hardware and construction companies who will pay you a deposit for those things. He also found tons of beer.” –LeakyLeadPipes

“Not a rave, but, when I lived at a party house in my early twenties, I once cleaned up after a big night and found a cigarette with lipstick on the end you typically light. The lipstick wearer had smoked it backwards and inhaled nearly the entire filter.” –Englishfucker
