A friend of mine was found with a chocolate (erm) willy - which he'd brought back for a joke.
He had to publicly destroy it in front of all the people in the immigration hall
For some reason Lorena Bobbitt springs to mind?

Not sure if you can get quality items but you can usually get Chocolate Liquors in Woolworths which are usually more cheap and chearful than the likes of Thortons or Hotel Chocolate so I wouldn't have thought a quality item existed.
