The Importance of Silence

I remember being heckled by some like 15 year old students, what sounded like at the top of the theater. It's like a 3000 seat, seat, seat of theater. So I'm carrying a halfway through, I get a text on my phone and forgot to put it on silent. My phone's going, oh, so that's, that's putting me off even more. And I'm tripping over my words. It's horrific. Just tell us what it's like when you do a joke but nothing happens.
