Skull of Saint Patrick

An American tourist travelling in Limerick came across a little antique shop in which he was lucky enough to pick up, for a mere $150, the skull of Saint Patrick.

Included in the price was a certificate of the skull's authenticity, signed by Saint Patrick himself.

Ten years later the tourist returned to Ireland and asked the antique shop owner if he had any more bargains.

- I've got the very thing for you - said the Irishman.

- It's the genuine skull of Saint Patrick.

- You swindler! - shouted the American.

- You sold me that ten years ago - and, producing the skull, added:

- Look, they're not even the same size!

- You have it all wrong - said the Irishman.

- This is the skull of Saint Patrick when he was a lad.
