There were three old gypsies came to our hall door
They came brave and boldly-o
The one sang high and the other sang low
The other sang a raggle taggle gypsy-o.

It was upstairs downstairs the lady went
She put on her suit of leather-o
Then there came a cry from the open door
“Oh lord - here now stand three dragons-o!”

雪とけて村一ぱいの竜ども哉

yuki tokete
    mura ippai no
        ryudomo kana

The snow is melting
    and the village is flooded
        with dragons.

I'll tell you a tale - now draw near,
We were down at the pub with a beer,
When, such a great same,
It all burst into flame.
Oh bugger, the dragons were here.

Happy families are all alike; every unhappy family is unhappy in its own way, until the dragons arrive.
