Off the top of my head:
"Uh, Hello, I see that you're all here, so, let's get started''

Then during the Drum Jam during Lateralus, it appeared that Maynard walked to Justin, then to the drummer from Big Business, and was giving them some candy. Then walked to his riser, and then tossed one at Danny.

After Lateralus
"[Something about how after all these years, it's still a challenge to play some of the songs] and I thank you very very very very very very very much for not using flash photography during tonights show. It helps us concentrate on performing and allows us to put on a great performance for you. Thank you very much. Now it's time for us to get back to our Pay-Per-View porn at the hotel room, but we have another for you"

It's close, not 100% what he said. I'm tired. I can't remember. Awesome show, except for the retards behind me (Sec. 115) who kept screaming at the top of their lungs during Wings/10k days.

Oh, and the sound was awesome. I could hear Maynard perfectly (except during Wings, he was kinda drowned out). But, the sound overall was awesome. No one instrument dominated over the other.
