"can no one take a joke. [an a la Stritch joke, to boot!]"
Because Stritch was twice as old as Patti when Stritch said it. There's a certain point where you let old broads say whatever they want to say and Patti hasn't reached that age yet.
Plus, Stritch had never won a Tony, despite over 55 years of turning in some excellent performances.
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
