@sun Oh yeah, that'll do it. You needed the other one too.

When I was in college, I caught some kind of sinus infection. At the time I had no idea what a sinus was, or where it was located. A buddy told me, "bah, it's just your snot rotted". Armed with such advanced medical knowledge, I pressed on the affected area until something popped, and a bunch of dark brown material exited my nose. But it cleared the problem!
