1-800-FLOWERS is not a phone number. The phone number is 1-800-356-9377. FLOWERS is just a mnemonic device called a phone word (https://en.wikipedia.org/wiki/Phoneword).

Maybe the document should be called falsehoods programmers believe about what people will provide when asked for their phone number.

What about e.g. KLondike-5-1234?

KLondike-5 is really just 555. Those old exchange names were made up from the exchange's assigned numeric digits. That's why both the K and the L are capitalized, and why e.g. ACademy, BAldwin, and CAnal were all the same exchange. Probably still a better example than 1-800-FLOWERS though.
