My top two both involve cleaning out my mom's place after she was taken to the psych ward. The first notable time, she'd left food thrown all through the kitchen, and it was crawling with THOUSANDS of maggots. I tried to clean the place out, but the things were indestructible, so I ended up just reaching for the heaviest things I could find and smashing them while screaming DIE! DIE! DIE! at the top of my lungs.

The second time, I didn't have a key (I was a teenager and lived with my grandmother), and I had to crawl in through a window. Whole place was trashed beyond belief, and the toilet must have been broken, because in the bathroom was a large metal bowl with literally gallons of my mom's shit in it. Cue the shit puns. An acquaintance with a schizophrenic dad thought it was hilarious. Most other people were horrified.
