What's the worst thing that's happened at your teenagers party or your party when your parents were away

i came back from a weekend away and found out my son had had a party. the garden was covered in bottles of booze and actually smelt like a pub. Old pizza and other fast food boxes were strewn around the house and garden..some crawling with maggots and flies. The dogs had done the toilet inthe upstairs landing and the poop was covered with my towels. Worst of all i found a used condom in my bed side tables drwer! I am sure there are far worse stories. Have you got any?
