What the hell just happened?

Sorry to bother you again but I nearly just threw up all over my keyboard and some poor schmo's tax return information. I have no idea why it happened I was just sitting here, minding my own business when my stomach started regurgitating the pizza I had for lunch. Fortunately I was able to fight it down but now I can't stop coughing and my coughs taste like puke. That was truly frightening. What would have happened had I thrown up all over my desk, I'd have to quit on the spot and leave my paycheck to cover the cleaning fees, right? Wow, I hope nothing like that ever happens again. Not good times, bad times.
