A chic makes a post on craigslist on Sunday, "Bring the Booze, I'll continue the Fun." The guy responds to the chic and says, "I don't have any booze." The chic responds, "of course not, it's Sunday..nobody does." The guy responds back, "Your such a mindfuck!" at which point the chic stop responding.
