There are so many in 'HEAT' but to name a couple how about...
The coffee scene with DeNiro and Pacino talking about life, dreams, barbeques & ballgames.
"...I will not hesitate, not for a second. "
The scene when Pacino figured out what the crew was 'looking at'.
"...us. The LAPD. PO-Lice Department. We just been made. Yes! Ha! Okay, muthafucka! "
The last 10 minutes of 'The Devil's Rejects'.
- Block!
