My luck, I'd take in a snoot full of water after the "blowing" part! Then I'd have a terrible underwater choking incident... and eventually get it all cleared up and continue my dive. The main problem with that would be convincing my buddy that I am ok while choking.
I did choke really bad underwater one time, and Rod was watching me cough hard and hold my reg in, and face turning colors, etc. He looked at me and gave the thumbs up sign... thinking that I really needed to surface. I shook my head no, and giving the ok... a really loooong ok sign, and our "just a minute" sign, and he soon realized that I just needed a second to gather myself and all was fine. After the dive, he said that it scared him to see me choke like that, but I was ok... I just didn't want to spit my reg out in the middle of it. I was kinda "concerning" for a moment, but in the end... not that big of deal. I felt good that I could deal with it and move on.
