There's an episode called "Digital Estate Planning" where his dad mocks him for his lack of business acumen: "In 1980, you said that video games, not moist towelettes, were the business of the future. Today, moist towelettes are stocked in every supermarket, while arcade after arcade closes."
This reminds me something my the teacher of my university public speaking class told us (in the context of doing research): No matter how trivial, esoteric or obscure the topic, there is someone on earth who has devoted their entire career to studying it.
I find myself holding onto and preserving general ephemera and just happened to scan a moist towelette package over the weekend.
My collection mostly consists of business cards and dry cleaning type carbon copy receipts. I need to better catalogue these and share online.

(Given that he audited classes for years, this very much strikes me as a class project based on his interests...)
