Where has Kathy Griffin’s comic MOJO gone?

Catch Kathy Griffin: Gurrl Down! last night?  The (un)special served as another in a string of disappointments from Mz. G.Remember when she was insightful, sharp, and funny?  What happened?  The hour was short on laughs.  In her prime, Kathy lasered in on the zeitgeist, but lately her guns need recalibration.  We don’t want to discuss Michele Bachmann, and it wasn’t even that good of a burn (though I appreciate Kathy’s efforts to discredit her before she becomes a legit Presidential contender in 2012.)
