taking a bite of chocolate cake and then accidentally inhaling the crumbs into your sinuses via the back of your throat.
Now, HOW did I manage that? I don't quite know. But I truly do NOT recommend it.
I was blowing crumbs out my nose for several minutes and now I have a sinus headache. Perhaps I should figure out how to do a saline flush.
So be careful eating crumbly cake! If you are like me, you will find ways to hurt yourself with it.
