What to Watch on Thursday: Strong guest stars on NBC sitcoms

Parks & Recreation (8:30pm, NBC) - Megan Mullally guest stars as Ron's ex-wife Tammy, who runs the local library and wants to take over Leslie's lot (formerly known as "Leslie's pit"). 

The Office (9pm, NBC) - Jim and Pam are forced to double-date with Michael and his new girlfriend, who just happens to be Pam's mom. I guess this is what Michael meant when he said a few weeks ago that he planned to "date her even harder." 

30 Rock (9:30pm, NBC) - I hate to dwell on NBC, but really, how often do we get a chance to do that? Brian Williams has a guest cameo tonight, and that dude is flat-out funny. Okay, I'm stopping with this and promise not to promote "whatever" is in the NBC 10pm slot. 

The Last One (10pm, UNC-TV) - This is a treat. It's local filmmaker Neal Hutcheson's Emmy-winning documentary on Popcorn Sutton, an Appalachian moonshiner who went into the mountains to make one last batch of liquor and let Neal come along to film. If you haven't seen this yet, you should definitely tune in. Sadly, Popcorn passed away earlier this year. 

Real Housewives of Orange County (10pm, Bravo) - It kills me to write this, but Adrienne watched the first episode and said it's pretty good. Apparently these women actually address the "controversies" going on since the end of last season (such as losing  homes and husbands) instead of denying and fighting about it (yes, Atlanta, we're looking at you).
