A few years back, a coworker and I were eating egg sandwiches at Long Beach before work. 2 guys pulled up in their new BMW and got out about to take a run. They have a dog with them which then takes a huge dump on the beach.
The boys watch, but don't clean it up.
I ask if they are going to take care of it and one of them tells me to mind my own business and run off. I then took the plastic bag from my sandwich and pick up the dog crap. I smeared it all over all the door handles of the car.
As we left, we dove by the boys I told them to have a nice day!!
