Well, we're not sure why late-2011 viral video sensation Shit Girls Say, which spawned a trillion imitators (only a few of which were good, though 'Shit San Franciscans Say' remains pretty quotable), deserves to become a book. But that is happening. The book comes out tomorrow. And now Canadian funnymen Graydon Sheppard and Kyle Humphrey are back with the long awaited (not really) episode 4 of 'Shit Girls Say.' And yeah, it inspired a small chuckle in us.
