I'll start. Apt next door is having a cockroach infected. 4 days ago, I was playing sims on my laptop, wearing my eyeglasses. Right lens got blurry, took off, huge cockroach was crawling across inside of lens. While I was wearing them. Freak out ensued.
Worked at Office Depot back in ~2012-2014. Was the lead tech, and was the primary hardware fix guy. Had a guy bring in this old dell clamshell case PC with an xp sticker. It and him already smelled...off. After discussing some issues (no power) and finishing the paperwork, I cracked it open. They came spilling out. Dead, alive, and various sized. All the droppings too. It was one of the first machines I refused to work on. The guy had no choice but to leave with it. Didn't really say much after that.
The only other PC that came close to that were those of chain smokers. Where the tar buildup was actually sticky to the touch, coating everything, outside and in.
