Wow! If you think Tina Fey’s humor is scathing, you need to check out Joan Rivers. I’d heard snippets of her on TV years ago, and didn’t think she was all that much. But I heard another snippet more recently and all I can say is OUCH! Well, I do find her funny, well mostly, some of her numbers are pretty harsh. But she does direct a lot of the really nasty stuff at herself. And by nasty I mean in both senses of the word, more offensive terminology and raunchy scenes than perhaps anyone else (though often I can’t understand the words of some of the raunchier comics, so I don’t bother). She is entirely shameless and unapologetic.
