McNulty and Bunk when they go to that one crime scene and just say the word fuck
"I defeated your uncle Victarion and his Iron Fleet off Fair Isle, the first time your father crowned himself. I held Storm's End against the power of the Reach for a year, and took Dragonstone from the Targaryens. I smashed Mance Rayder at the Wall, though he had twenty times my numbers. Tell me, turncloak, what battles has the Bastard of Bolton ever won that I should fear him?" - Stannis Baratheon
Definitely the Lethal Weapon guys . Great onscreen chemistry together. Watched the extras on one of the DVD's a while back and a lot of the back and forth stuff between them was completely improvised and just kept in the movies because, well, it worked lol.
