End result: went home with an unsigned playbill, did not get a chance to politely congratulate his excellent performance, but did feel like my sarcasm under the circumstances of large people nearly smashing me was sharp enough to garner me my own stand up show. So it was not a complete waste. Of course, this is me being ungrateful, I did see his entire performance from approximately 15 feet away, it was impressive.
