Name that movie!

"We had a meeting, and we drew straws, and we got you."
"You got me? What do you mean you got me?"
"If you get killed, we take the rifle and avenge you."
"And we see to it that there's always fresh flowers on your grave."

And they did. More:

"That's a mighty big comfort."
"I told you he would appreciate that."
"Well now, don't you kids be too disappointed if your plans don't work out."
"We won't. If you're still alive we'll be just as happy."
"Maybe even happier."
"Maybe."

Damn, there is so much good stuff in this movie! Maybe more quotes another time.
