When, oh when will our wish be granted, highlighting the OP's subsequent posts in green. Daisymae confirmed within an hour and within the first 10 posts that it must be a paper knife, which is what most people thought it was. Notwithstanding, the thread has gone on for 3 pages repeating the same things.
Actually - scrap that. There has ensued an interesting and amusing discussion on what people have found in crackers and what they have put in them.
I'm probably just jealous because it has been made so difficult to get hold of them here. First you weren't allowed to bring them back in hand luggage, then they extended the ban to checked-in luggage. You're not allowed to post them. And it's an awfully long way from us to go by car, in which, presumably, you would be allowed to transport crackers. They are available in Germany but very rare, and anyway, they wouldn't have the jokes in them. I must remind myself next year to order some from the expat shop well in advance.
Happy New Year everyone!
