Serious Eats sent a list of things to do with a wooden spoon besides using it to stir.
They used my idea (only in a slightly different way) under "Ajar".
It showed how to keep the oven door open just a little to speed up the cooling down with a wooden spoon stuck in the door.
I had to use one with much more dexterity when my first stove (rented house) WAY back when and the oven temp guide was worse than useless.
This was also WAY before cakes mixes were invented. But I learned how to keep the temp correct (enough) by using different parts of the spoon and varying how the spoon was cocked/inserted. I rarely had a failure.
Necessity is the mother of invention.
