Remington side by side: Army of Darkness "THIS...is my boomstick!"
I've always liked the scene at the end of Saving Private Ryan where Tom Hanks is shooting at the Tiger with his 1911. He's wounded, dying really, the tank is about to cross the bridge. He pulls the .45 out, fires 6 rounds to no effect, the music swells, he fires the final round.....and the tank brews up in a huge fireball. The look on Hanks' face is priceless, and Spielberg timed the shot upwards at the Mustangs flying overhead after (presumably) FFAR'ing the Tiger absolutely PERFECTLY, just long enough of a pause to almost sell you on the idea that maybe he did kill that big chunk o' steel with a pistol!
