Then there was the famous snail in the ginger beer bottle.....I'm sure you know that one!
I'm having all sorts of fun learning these at the moment
but they are for the most part much more interesting than statutory law. Besides, some (such as the Carbolic smoke ball company) sound so improbable that i'm sure that you could make other cases up as required - i've been tempted to reference
Grenouille v National Union of Miners to see if anybody notices...
(
Donoghue v Stevenson btw - edit: d'oh, FNG beat me to it... )
