When I was in my 20's I worked with this guy at this signage/awning place.
Each unit in this little strip of stores we serviced had a swamp cooler for cooling it. Well this tenant in one unit was just being a giant ass douchebag to us one day when were there changing lights out and updating the front building marquees.
Things go on, we just do his shit quick to get outta there and move on.
So after we get wrapped up with the rest of the job, and get to packing up, the guy I was working with grabs the tall extension ladder, and dissappears around back.
Comes back a few minutes later, we finish loading up and leave.
Dude starts giggling, and I'm like what man? What's going on?
Takes him a minute to not laugh long enough to tell me he just took a big nasty shit in dude man's swamp cooler reservoir.
Omg I cry laughed along with him.
Thought it fitting for such an asshole of a person.
Still know the guy, and he and I still giggle about it every now and then.
