Well I'm sure glad you didn't choke. I never experienced that flood of saliva but I know from my more minor near-choking incidents that it can hurt and scare you. Did it make you realize how important it is to learn some basic heimlich maneuvers?...obviously to use on someone else choking, not yourself...it made me learn it.
When I first saw the partial title of your post "brocolli stuck in my food" it reminded me of when I was a young boy and used to make forests of broccoli in my mashed potatoes and roll the giant boulders of peas through the forest...and then I ate the whole world.
