If You’re a Pirate and You Know It

Tune: If You’re Happy and You Know It

If you’re a pirate and you know it, swab the deck (Swish, swish)
If you’re a pirate and you know it, swab the deck (Swish, swish)
If you’re a pirate and you know it, then you’ll hear the sea winds blowin’.
If you’re a pirate and you know it, swab the deck (Swish, swish)

(Repeat the song with “Walk the plank” (Stomp, stomp) & Say ahoy: Ahoy! (Wave hello)

Another Version: 
If you're a pirate and you know it, clap your hands.
...stomp your feet.
...say "Arr!".
...do all three!
