i have no idea . . .

get yourself some happiness by making it . . .

obviously this is a case of 'engrish', when the japanese make mistakes in their printed english. why don't the writers get their work checked before putting it up in public? how bizarre! maybe they don't mind that it's wrong, figuring people who read it here in japan (except for native english speakers like myself) will have no idea that it's wrong either. who knows.

the meaning is easy to understand, it's just grammatically incorrect. i think the general meaning is: make your own happiness!
