Amy Poehler played her final ASSSCAT as UCB on Sunday night.

From Time Out:
At the top of last night’s ASSSSCAT performance, Amy Poehler joked that she was superexcited about this year’s New Year’s slogan: “Two-thousand mine.” In fact, 2009 probably will belong to her.
The 9:30pm show at the Upright Citizens Brigade Theatre was the comedian’s last before heading to L.A. to shoot her new NBC series, which will air later this year. (It’s now dubbed “The Untitled Amy Poehler Project”; creators Greg Daniels and Mike Schur finally got people to stop calling it “The Office spin-off.”)
As the last member of the original Upright Citizens Brigade in New York, she’ll be sorely missed at the long-running Sunday night improv shows (last night’s also featured 30 Rock’s Jack McBrayer and John Lutz, former SNL player Horatio Sanz, and Conan writers Kevin Dorff and Brian Stack).
However, we have a feeling she’ll be back sporadically, and perhaps for longer, once shooting has wrapped for the season: Word on the street is that she much prefers New York.
