Liberals have solutions to all problems. Newly developed wall paint will piss back at you when pissed upon. Great! Now the homeless will walk around SF with their shoes & trousers pissed upon & smellier than ever! Smarter ones will learn from ladies how to piss into the ground. Lawyers will sue the city for sex discrimination because this new paint will work only against the men. And $500 fine will do wonders – all these street vagrants usually keep thousands in their pockets! Look at the demonstration below.
