Coworker was a world class dick bag. He hated my guts and I wasn't his biggest fan either, he tried getting me fired from the first week I was working there. I ended up working there for at least a year and a half if not two years.
Imma quickly describe the job, I was a mall security, night shift. I was alone from 9pm to 6am. I used to smoke weed in the security office daily, like on average 3 spliffs a night. I got to know one of the guys that worked at the liquor depot, he had a nice discount, I send him a 15$, he'd get us a nice 12 pack and a little mickey. Man lived in the neighborhood, so he'd stay late and go home when it's near oppening time. I used to get high at work on the nightly, and used to get drunk at work at least twice a week.
Anyway one faithful day I come to work, and I find out I get blamed for a whole bunch of shit that was completely unrelated to me, and said coworker made some serious attempts to get me fired. I was coming close to the end of my tenure there because I was going to have to leave that job so I could complete my teaching practicum, it was at least 2 weeks away. Once I was alone at work and closed up the mall doors, I got high and super drunk. Throughout that night I did not use the bathroom
I consistently sprinkled his uniform whenever I needed to relieve myself, I peed a lot. I eventually needed to poop, so I laid a healthy one lump sum deposit in one of his boots and wiped my ass on his uniform

I stopped peeing on his items around maybe 4am so it could dry up

I hesitated about leaving the poop in the boot, but in the end I valued one more paycheck before leaving then leaving with him knowing I pooped in his boot, besides he'd reek of piss and would walk around with my shitstain on his back while patrolling mall
Never got caught.
