challenged

Comedy "Silverman has two advantages comics here perhaps don't - she performs to a nation still a little more innocent, still capable of being challenged by comedy. Her other is that she doesn't do characters - or rather she does only one character - the beyond-Sarah, the Frankenstein Sarah. 'I actually think of it as a character,' she says. 'I mean, I don't have a weird voice or always have to be angry. I'm completely myself on stage. I talk the way I talk and I move the way I move, but inside, I think she's more obnoxious, ignorant yet arrogant.'" -- Alex Renton of The Observer profiles Sarah Silverman
