Didn't have a clue what to expect, but it was fun!  Joan Rivers was very complimentary and seemed to genuinely like and admire Grace.  And Joan had done her homework - that always gets a gold star from me.

Grace drops a new tidbit of information into many of her interviews, tonight was no exception. 
There was a segment about three stars wearing the same dress that involved Meryl Streep. Grace said she had to chose Meryl because her mom had gone to school with her. How cool ! :)
