answer:That happened once – speaking to a crowd, zipper was open. Nothing hanging out, but still embarrassing. I said ‘excuse me” into the mic, turned around, fixed the problem, and moved on. Took all of 20 seconds. No one cared. I had a different embarrassing problem – I was taking some medicines that make you urinate frequently and strongly. That day I was teaching a training course – people had driven in from 50 miles away. Middle of the class, the urge struck. No choice. I smiled, said excuse me, it’s my medicine, went to pee, and then continued the class. It happens to everyone… it feels terrible to you when it happens, but the audience never remembers a thing.
