The day I saw Whoopi's show, she stopped it at least twice. Once because some audience member called out to Whoopi and said she was unhappy with her seat. And, Whoopi told the ushers to move her!
And, then the second time, there were other people complaining really loud that someone was talking on their cell phone in the theater. Whoopi stopped the show again, had the house lights brought up, and berated the woman! It was the strangest thing.
She then returned right into the place she left off in the skit. I reckon you won't see this on the filmed version of the show!
