A friend of mine was doing some computer contract work in the Netherlands. A (British) friend of his who was already over there, asked him to bring some confectionary she was very fond of but could not obtain in the Netherlands, with him; namely, Cadbury's Cream Eggs.

He also put his Walkman in the case.

So, as he goes through the X-ray machines at the ferry terminal in the Hoek van Holland (sp), his suitcase contains a small box with circuitry, and 12 oval opaque objects, about the size of small hand-grenades (Cream Eggs are wrapped in foil).

It was all sorted out in the end, though he had to eat one of the Eggs to prove it was innocuous. This apparently revolted the Dutch customs guys, even though they are supposed to remain unmoved at what people- and drug-mugglers can do.
