A Series of Unfortunate Events: The Dismal Dinner by Lemony Snicket
So, while reading some stuff about Netflix's A Series of Unfortunate Events, one of the lists of stuff they could adapt mentioned this in passing. Being the only ASoUE work I'd not heard of, I looked it up. Turns out it's just a short 'story' that was given away with kids' snacks as part of the promotion for the 2004 film, and you can even read it all online here. Which I did. It was as pointless as its provenance suggests, but hey-ho, that's free gifts with kids' snacks for you.
