As my late cousin would say, "just pee on it." And while that's great advice you must first take into account whether or not you are a fugitive.
Edward Nathan Jr. had to pee and he wasn't about to find a restroom. Unfortunately for him, he was arrested for public urination. That's when the cops took his finger prints to find out that he had been on the run for nearly 30 years after escaping the Tampa Community Correctional Center in 1983.
At least now, he'll always know where to find a bathroom.
