From the episode "Pirate Treasure" and is on the DVD "It's Great to Be a Ghost"
Uniqua:
If you wanna be a pirate, get up on your feet
You can’t be a pirate if you’re sitting in your seat
Swing your arms tough, and stand kind of low
And make this noise wherever you go
Arrr! Arrr! Arrr! A pirate, a pirate, a pirate says Arrr!
It might seem strange, just a bit bizarre
But they know you’re a pirate when they here you say Arrr!
Austin:
Arrr! Arrr! Arrr! A pirate, a pirate, a pirate says Arrr!
You wear a spare part, a bandana and a scar
And they know you’re a pirate when they hear you say Arrr!
Uniqua:
The Jolly Roger is the pirate flag: a skull and some bones on a big black rag
We’ll fly it on our ship, high above the sails, and we’ll search for treasure and be tough as nails!
Both:
Arrr! Arrr! Arrr! A pirate, a pirate, a pirate says Arrr!
If you think we’re noisy, you’re right, we are
‘Cause they know you’re a pirate when they hear you say Arrr!
A Pirate says Arrr! [Part II]
Pablo:
If you wanna be a pirate, sail the ocean blue
You go and steal some treasure, 'cause that’s what pirate do
Tyrone:
We laugh a pirate laugh, dance a pirate dance
We wear a puffy shirt and some baggy pants
Both:
Arrr! Arrr! Arrr! A pirate, a pirate, a pirate says “Arrr!”
We sail a pirate ship, we don’t drive a car
And they know you’re a pirate when they hear you say “Arrr!”
Tyrone:
“Arrr!” mean yes, and “Arrr!” mean no
Pablo:
And “Arrr!” means come on mates, let’s go!
Tyrone:
Say “Arrr!” when you’re happy
Pablo:
And “Arrr!” when you’re smelly
Tyrone:
And “Arrr!” when you’re having your pirate toast and jelly
Both:
Arrr! Arrr! Arrr! A pirate, a pirate, a pirate says “Arrr!”
If you think we’re tough, you’re right, we are
‘Cause they know you’re a pirate when they hear you say “Arrr!”
If you wanna be a pirate, get up on your feet
