Question Everything

Back when I was a semi-retired minor league basketball assistant coach, I had all these great catch phrases that I'd belt out during games. "Vampires in the sky, Brian!" or "Mushroom that blockhead!" Well the other day I found out that I've got this bizarre disease where my voice cannot be heard by anyone except for myself. Turns out, I've always had this disease. I guess that makes a lot of sense, considering all the communication problems I've had over the years. But it does yield the question: What was everyone cheering for when I started yelling out my amazing phrases?
