Dumb Patrol (1964)

[last lines]

Bugs Bunny : He's heading right for the ammunition dump.

[explosion]

Bugs Bunny : I've heard of Hell's Angels, but I never thought I'd see one.

[Bugs Bunny then sees Yosemite Sam's spirit, rising, and playing a harp, as cartoon concludes]
Bugs Bunny : Well, what do you know? There's the little Wiener schnitzel, now. I'll just drop him this little token of my esteem.

[while flying over him, Bugs Bunny dropped a note to the Baron Sam von Schpam]

Yosemite Sam : What's this?

[Baron starts reading note, dropped by Bugs]

Yosemite Sam : Uh, "Dear baron: Roses are red, violets are blue, a leghorn's a chicken, and so are you!" Why, that dummkopf! He even spelt "baron" with a small b!

[Baron is back to reading note]

Yosemite Sam : PS: I enclosed a big "B" in the flowers.

[a yellow-jacket stings the Baron's nose]

Yosemite Sam : Yeow!
Yosemite Sam : [after crashing his plane into a mountain and falling toward the ground] Ooh, That dirty snickle kopf, ach und strudel heden Schlieffen kopf!

Mel Blanc: Bugs Bunny, Yosemite Sam, Porky Pig, French Officer, German Officer
