"A pirate bunny is fun to be,
'Cause it is a glorious thing!
I'm in my trouser.
It is a glorious thing
To be a pirate bunny!
I'd rather have an eyepatch
Than a nose.
Oh, he has a thing to keep his eye in.
It's on his forehead
Where his eye should be,
So it can see.
And it's even more a glorious thing
To be a pirate bunny!"
There was a lot more, about swords and things, but I couldn't catch it.
