Will: You are a terrible best friend. Terrible! You totally ditch me every time you have a boyfriend, and then you come crawling back when you're heartbroken. You don't listen to me. You don't even seem to like me. You get obsessed with the play and totally ignore me except to insult me to our friend behind my back, and you exploit your life and the people you say you care about so that your little play can make people love you and think how awesome you are and how liberated you are and how wondrously gay you are, but you know what? Being gay is not an excuse for being a dick.
The ending when all the Will Graysons say they appreciate Tiny Cooper.
