The biggest audience reaction to a blooper that I've ever seen wasn't for a singer. A young married woman was giving a presentation for a household disinfectant, at a direct marketing seminar. There was a lag of a couple of seconds before everyone really processed the fact that she had just extolled the ability of the product to "kill all kinds of orgasms"; then the roof blew off. She spent some time with her face buried in her arms on the podium before she emerged red-faced to struggle on.
