Dry
In the morning, you use a gun on your nose to make it dry.
Don't worry, there aren't bullets in the gun. It's an air gun! So just imagine shooting the air into your nose every morning to make sure it's nice and dry.

This technique for a nice dry nose was invented by Genghis Khan (かん)! Well, not him, but someone who worked under him. You see, he had a bit of a damp nose problem.
Now the next time you manage to get your nose nice and dry, think back to our founding father Genghis Khan and thank him for where you are today.
