Her show has been a real surprise for me too. The episode I saw she was planning jokes for a benefit, and she said her nightmare is that she does a Mary Kate Olsen joke and then MKO dies. Her husband, completely deadpan, says "that would be horrible". It was hysterical! (or maybe you had to be there). Not all of her stand-up is funny but she seems "real" in her show. Compare that to say, Raven, who I just saw with a make-a-wish child on a clip on Disney Channel (they were on the Magic). She was saying how this kind of thing makes her celebrity all worthwhile and sounding fake as a $3 bill.
In my dictionary, the picture by "annoying" is Fran Drescher.
