Same
There's a mustache on the ground. Upon closer inspection, you see that the mustache on the ground is exactly the same as yours!
どう
おな
None
When we need to remember the reading どう, we use the word "doughnut".
While this is already strange enough, you notice something stranger. Over a couple feet away is a doughnut (どう) who also has the same mustache as you (and the one that fell on the ground). The doughnut looks at you for a moment, then scampers off. This doughnut must be a mutant because normally doughnuts don't move.
