Wayddahgo JG. In addition to those bodily noise things, don't pick your nose either.
From my vast
stage experience. Take a deep breath, be cool, "act" like you've done this a 1,000 times. You're the man. They came to you. They like you...no, they love you. Don't slouch, but don't sit up too straight, ask to go to the bathroom, no, ask for permission to go to the bathroom and when you come out, come out blastin.
Unfortunately I'll will away from all electronic media at that time of day. But Good luck and break a penis,,,I mean leg.
