When you write something important down on a Post It Note so you won't forget it, and immediately misplace it.
You: "Hey, do you have the contact info for that big account we're working on?"

Co-worker: "I wrote it on a Post It Note, but I can't find it! Have you seen it? Help me!"

You: "Post It Not, loser!"
