Re: Symbol unknown.
By jove! You have found one of the five secret amulets, each of which were placed inside a milk chocolate bar, which would allow the finder a free day pass to the secret workings of a mysterious candy factory owned by an awkward and eccentric millionaire confectionist - Gene Wilder. You luck is truly with you my friend.
I am envious.
It's amazing to me that, unlike in the real world, people on the internet will wear "everyone thinks I'm a moron" as a badge of honour.
