...never having seen it before what would they be?
Mine:
1) Gus takes out cartel and pukes himself while walking out of bathroom with camera behind him. Salud.
2) Train Robbery to motorcycle surprise. Dead Freight.
Gus yelling on the pool deck - '...take what you can and leave or come fight me...'. something like that.
That blew me away knowing he was poisoned. He was so committed to revenge.
Walt runs over the two drug dealers before Jesse bites the bullet,
And Hank takes out the twins in the parking lot.
Just a couple more to add to the already mentioned good ones.
