Did anyone notice that Mary really began to ham it up during those last few months of the original group being together? I noticed it while watching Flo's last appearance on the Tonight Show and Sullivan. She also began to ad-lib more and more during this period too which she had never done before. I wonder if this was her way of saying "Hey look at me, I can be funny and entertaining. I'm not as easily replaceable as Flo". Whereas during this period Flo seemed extremely introverted.
