My favorite is the very last line from the movie A Boy and His Dog (1975):

"Now listen up, you primitive screwheads. See this? This... is my boomstick! The 12-gauge double-barreled Remington. S-Mart's top of the line. You can find this in the sporting goods department. That's right, this sweet baby was made in Grand Rapids, Michigan. Retails for about $109.95. It's got a walnut stock, cobalt blue steel, and a hair trigger. That's right. Shop smart. Shop S-Mart.

But I'd have to add the T-Bone line from Tommy Boy.. of course when he keeps screwing it up.

The only problem is that in this job is there's just no place to hide. It's not like having a bad day selling log cabins. You have a bad day here and somebody dies... and that's just not f***ing good enough.

- Kurt Russel as Lt. Stephen McCaffery - Backdraft

'Beavers and Ducks' - Billy Bob Thornton, Bandits

I had always heard your entire life flashes in front of your eyes the second before you die. First of all, that one second isn't a second at all, it stretches on forever, like an ocean of time... For me, it was lying on my back at Boy Scout camp, watching falling stars... And yellow leaves, from the maple trees, that lined my street... Or my grandmother's hands, and the way her skin seemed like paper... And the first time I saw my cousin Tony's brand new Firebird... And Janie... And Janie... And... Carolyn. I guess I could be pretty pissed off about what happened to me... but it's hard to stay mad, when there's so much beauty in the world. Sometimes I feel like I'm seeing it all at once, and it's too much, my heart fills up like a balloon that's about to burst... And then I remember to relax, and stop trying to hold on to it, and then it flows through me like rain and I can't feel anything but gratitude for every single moment of my stupid little life... You have no idea what I'm talking about, I'm sure. But don't worry... you will someday.
