Mutiny on the Bunny (1950)

Yosemite Sam : [handing Bugs a mop] Here! You're a-swabbin' the deck.

Bugs Bunny : Oh, no, I'm not.

Yosemite Sam : Oh, yes, you are!

Bugs Bunny : Oh, no, I'm not.

Yosemite Sam : Oh, yes, you are!

Bugs Bunny : Oh...

[dissolve to Bugs mopping the deck]

Bugs Bunny : Yes, I am.
[first lines]

Traumatized Sailor : [fleeing from Sam's ship screaming] I was a human being once...

[Sam notices the sailor, who runs off]

Yosemite Sam : Avast there! Come back here, you barnacle-bitten swab!

[Sam fires his pistols in frustration]

Yosemite Sam : Blast his scuppers! Now I gotta get me a whole new crew. I'm a-sailin' with the tide, or my name ain't Shanghai Sam... and it is.
Yosemite Sam : Ooh, belay there, you long-eared galoot! Get aloft and furl the tatter-sole top gallants before I keelhauls you!
[last lines]

[Bugs has forced Sam to become his pilot on a voyage around the world, using a lifeboat]

Bugs Bunny : Oh, the places I've been and the things I've seen. Come on, come on! Step on it! We've still gotta make Rio de Janeiro.

[the boat sails off into the sunset as we iris out]
Mouse : [With Irish broque, waving goodbye to Bugs Bunny] He's not long for this world!
