Second to last scene of season finale of Season 2, with Tony smoking the cigar and Keith Richards' "Waiting on a Call from You" playing in the background before cutting to ocean shore waves and sunset...this is shortly after they killed Pussy on the boat and dumped his body in the ocean...
At least it's a good one anyway...
Paddy! On to it! Definitely my favourite scene, that just oozes of cool when Tony in slow mo exhales the smoke from that cigar. Awesome.
