I am a little Budgerigar, (Flap arms)
I have a big belly-ache, (Rub Belly in circular motion)
Because the people that I live with, (Outline a roof with fingers)
They are so stingy, (Hand out food)
They feed me herring every day, (Make wave motion with hand)
And I don't like that at all, (Shake head from side to side)
Oh I'd rather, yes I'd rather, (Nod head up and down)
Drink Coca-Cola, (Drink from bottle)
And Ice Cream, (Lick Ice Cream Cone)
Repeat the song with the actions in the (exaggerared) style of various nationalities. eg:

Japanese: Very Tiny,
German: Rigid & precise,
