Quote context

[...]

- Mr. Koufax is a really cool guy. Wish my dad was as cool as him.

- See, my dad was a military man. Guess I wasn't such a good soldier. When I was 35 years old, he attempted to give me a crew cut while I was sleeping one afternoon. I woke up, broke his arm, haven't seen him since.

- I'd rather live out on the streets than under his freaky-ass rules.

- Anyway, I think Mr. Koufax should be acquitted of all the charges.

- If OJ can get away with murder, why can't Sonny have his kid?

- This guy knows what I'm talking about.

- No more questions.

- And how long have you been delivering food to Mr. Koufax?

- I deliver food for six years. Plus, I'm stripper. But I've put on weight, so it's problem.

- I see. And in your experience, was Sonny a good father to Julian?
