Two budgies

The two budgies or ttb alliance, is a secret alliance in which one must not speak off, he who knows of the two budgies must not speak of the two budgies, if a member of the ttb, has shared the secrets of the ttb alliance, you must the become a member, or you must face harsh punishments

Have you heard the two budgies sing, to white one would reply, yes I've heard such cheerful song
