I like that test that Sonny gives C.

"All right, listen to me. You pull up right where she is, right? You go to get out of the car and you lock both doors. Then get out of the car, and you walk over to her, and bring her over to the car. Take out the key, put it in the lock, open the door for her, and you let her get in. Then you close the door for her. You walk around the back of the car, and you look through the rear window. If she doesn't reach over and lift up that button so you could get in, dump her. Just like that? Listen to me kid, if she doesn't reach over and lift up that button, so you could get in, that means she's a selfish broad, and all you've seen is the tip of the iceberg. You dump her, and you dump her fast."

So true.
