I think Patti's "Shut up!" bit would have been pushing it had she been boasting about her Tonys like all the presenters or simply rambling on about the show/whatever. But she had a list of people to thank, and it was obviously very important to her that all of them be included. I thought it was actually kind of touching how much she cared about mentioning all of them.
And also, who HASN'T wanted to scream at the orchestra when they start playing over good speeches? Hell, I've done it in my living room. Probably wouldn't do it at Radio City, but that (among other things) is what separates me from Patti LuPone.
As for favorite speeches, mine are along the same lines as everyone else's. Loved Patti's, actually cried at Laura's, and having never liked Lin, suddenly loved him. The "Finishing the Hat" reference made my life, as did the line: "It's too darn hot, like my man Cole Porter said."
I chose, and my world was shaken. So what?
The choice may have been mistaken. The choosing was not.
