Titles of fiction works -- enthusiasts jumping to conclusions?

Prompted by my browsing today on a message board on which I spend a good deal of time; it's North-America-based, and discusses pretty well "all and any" subjects. On a thread-heading in this board's section which discusses "the arts" in the term's widest application, my eye was struck by the word -- without further clarification -- "Letterkenny".

Of course, for railway enthusiasts with a nostalgic and minor-railways bent, that word brings straight to mind the town in County Donegal, and long-ago 3ft. gauge railway hub. Full of curiosity, I clicked onto the thread. I discovered that "Letterkenny" in this context, is the title of a currently long-running sitcom series on Canadian television, with a great following in those parts. A thing I'd never heard of; but as well as my not living in North America, I am pretty much oblivious to anything telly-related, anywhere. Am wondering whether there are people in Britain, who know of this Canadian series?

Said series -- from what I could Google -- would appear to be in a relatively upbeat and affectionate vein, and set in a country town in (English-speaking) Canada -- the chief characters, two young guys who live in this town, and their love interest. The town concerned is Letterkenny, Ontario: seemingly a fictitious community, but named after the real place in Ireland which bears that name.

Train of thought -- re this name leaping at me out of the blue -- proceeded to the stereotype: of chaps who pursue our hobby, often being viewed by people who don't, as being more than a bit one-track-minded, and out of touch with non-railway matters. Usually, we seem to enjoy laughing at ourselves; in the spirit maybe, that "if we don't -- the 'normals' will laugh at us anyway". One feels that there should be -- and maybe there is -- a genre of jokes about the railway enthusiast who went to see / started to read / whatever, such and such an artistic offering; and was upset and disappointed by its not being about what he had expected from the title. For instance, the enthusiast who went to see the film Trainspotting... any others in this vein?

I remember from my younger days a complaint in the paper from two old ladies who went to see Fritz the Cat expecting a film about cute moggies.

The Striker comic in the Sun once had a scene where a character and his girlfriend have just finished seeing The Mummy, while the girlfriend complains that he said they were going to see a film about a woman bringing up her kids.

The character then orders prawn crackers in a French restaurant and, when told that the restaurant doesn't serve Chinese, asks what they did to the waiter to warrant it.

Thanks for responses to what I've been feeling to be, my rather silly OP (and I wasn't even drunk)...

There is the tale of the Renewable Energy Scientist who went to see Gone With The Wind -- expecting it to be an educational film to do with his speciality, which he could critique; and walked out in disgust, when he found that it was about the stupid American Civil War.
