I need to find an english version of "Calimero" a cartoon about a small black bird with half an egg shell for a hat.

There is no such thing. Have you heard that there is an
English version?

Yes it was on Australian TV in about 1974 (in english). He used to say "Its an injustice it is!"

Did he also say 'why you cry'?

I remember it being on around 5.15 before Crossroads and it was in english.. must have been around 1974

You can find one episode in english on the official site :)

No but he did say "everbody is always picking on me"
