The Man-Law approved way to clear your sinuses.
During a really hot shower, push one nostril closed with your finger and exhale as hard as you can through your other nostril. Repeat as necessary. Then switch nostrils, and repeat as necessary. Leave big glob(s) of snot on shower wall/curtain for woman to clean up.
Sometimes it takes a crazy person to see the truth. If so, I'm a freaking lunatic.
