Unbelievably good dialogue!
"Here, I tell you what I want you to do. I want you to make me a list, see? I want to see it in writing. I want to know all the the things that are wrong in your life, all the things that can go bad. Here's a pen! Write! Start writing! Whole list! All the bad things! Write! Well, why aren't you writing? WRITE!!! ...I'm out there spending too much money on clothes, trying to look like maybe I'm under 30 so that somebody will hire me and you're sitting in here whining like an idiot! ...I will get a job, allright!? I will get you to Monterey before your birthday! I will get you in school by September! I swear it! SHALL I OPEN A VEIN AND SIGN IT IN BLOOD?!!!"
That last line in particular had me in stitches!
What are some other great lines?
