I was explaining to a coworker that my Contigo brand coffee travel mug was a great mug except that it was just impossible to clean properly. I explained to him that as a result, I had forcefully removed the guts to my mug lid.

In the midst of explaining this, I showed him which mug it was on the manufacturers website (we were remote- this was all via Slack) and as I did so, I saw the animation that explains how to disassemble it for cleaning.

oof.
