Arnett Parks at NBC Again

Will Arnett, formerly George Bluth II on Arrested Development and the devious Devon Banks on 30 Rock, will finally make a cameo on his wife Amy Poehler's sitcom Parks and Recreation in an episode that will likely air January 14. Poehler hinted at the cameo at a recent Paley Festival event. What remains to be seen is if Will's greatest comic foil will be present -- though I imagine the sexually oblivious grin of Jack McBrayer is overbooked at this time of year. [E!]
