Chopper The Blue-Nosed Reindeer
With apologies to Stan Boroson.
(Sung to... you guessed it, Rudolph the Red-Nosed Reindeer.)

L: Yanno, Sanji, this tune about Prancer and Vixen?
S: Yeah?
L: Sounds mighty fine, but the words need some fixin'.
S: Oh no....
L: Though the tune's the same, we changed ole Rudolph's name.
S: Stop. Now.

L: We call him Chopper the blue-nosed reindeer.
S: I mean it.
L: Had a funny-lookin snout.
S: Please?
L: So Zoro cut his nose off.
S: Ow
L: Just to try and smooth it out.
But when he put his nose back on,
Usopp got it upside down!
S: Sheesh.
L: Now every time the rain falls,
poor ole Chopper nearly drowns!
S: ....

L: Then one snowy night aboard,
Nami came to say,
"Chopper with your nose so blue,
why you hide, what's the matter with you?"
S: ???
L: Cause Chopper hid beneath the bed,
shaking so with dread and fear.
Chopper's a good doctor, I guess,
But he's a very strange reindeer!
S: I must hurt you now....
Z: Allow me.
