To me the lines in GTA IV were pretty forgetable and some of them were forced.
- POLICE MOTHERf*ckER, PULL OVER RIGHT NOW. Unfortunately I was being pursued and out of nowhere a cop car rammed me saying this very line, I died, both of laughter and in the game.
- f*ck you bitch ass!
- You have the right to shut the f*ck up!
Some of those make me chuckle or slightly laugh everytime I hear 'em.
