Maybe tell them about the digestive benefits.

Excellent! I like it.

Is this a Futurama reference?

I think you are, like I did, interpreting “sticky side down” as meaning “sticky side against the surface to which you’re attaching the note.”

I don’t want to speak for the OP, but I think they meant “sticky side down” as “still against the wall, but at the bottom of the note, rather than with the note hanging from the sticky side at the top.”
