The Berk National Anthem is the song of the Hairy Hooligan Tribe in the books.
I didn't mean to come here,
And I didn't mean to stay,
But I lost my heart to these rainy bogs,
And I'll never go away!
I've heard that the sky in America,
Is a blue that you wouldn't believe,
But Berk is my lobster after all,
And now I'll never leave.
I was on my way to America,
But I took a left turn at the Pole,
And I lost my shoe in a rainy bog,
Where my heart got stuck in the hole!
- The line 'But Berk is my lobster after all' refers to lobsters mating for life, and are thus symbolic of love, so to say something is your lobster, means that it is your forever.
