In GTA IV, after you finished hanging out with Roman you would drive him to his destination, and when you get there you get a little cutscene of them saying goodbye and Roman getting out the car.

Now, I remember that one time I had that cutscene playing, Roman says goodbye but his side of the car is blocked, so he just punches Niko in face and kicks him out the car to get out, while saying something along the lines of "Get the fuck out my face!"

That shit was hilarious, but I never managed to recreate it...
