I know it's an old topic, but I had one last night I just HAD to share.
A grown man, in the 4th row, kept making squalling cat, and very loud bird calls. Through the whole show.
It's a show in which there is no such thing as a fourth wall, and a few sections of ad-lib lines. During one of them (rife with the squalling cat noises) my lead said, "Someone is starting to wear on my nerves." At which point the offender yelled back, "Isn't that what they pay you for?!" We just ignored the man the rest of the show, and eventually his companion got him to calm down.
Unfortunately, he wasn't in a place where the house manager could get to him without making an even larger disrution than he was making. Though if he kept it up at his initial intensity I WAS going to use the God-mic. It's the sort of show where I could have gotten away with it, and been pretty scathing, too. (My cast would have adored it)
Dr. Dolittle, over there, was also the only one who did not stand in the standing ovation. Jerk.
