When my sister was giving me her new phone number, she offered a handy mnemonic device to remember it. The last four numbers were 1-6-0-2 and she brightly told me, "And you can always remember it because that's the year Shakespeare's Twelfth Night was first performed!"
I laughed because of course that's exactly the first thing I would think.
A few years have passed but I think about Twelfth Night every time I dial her number. She'll be getting a new number in a few weeks and you have no idea how much I am hoping it contains a date with some significance to Elizabethan literature. I'm waiting for her to call and say, "And you can remember it because that's the year Christopher Marlowe died!" or "This one's easy because it's when John Donne became an Anglican priest."
Please, please phone-number-assigner guy. Give her a good one.
