It may be wasting an hour every night indulging Jay Leno, but when it comes to sitcoms NBC is making its way back to Must-See TV. While “30 Rock” remains its crowning jewel (the “too soon” joke in last night’s episode was one of many that destroyed me), “The Office” has a steady following, and now it looks like the new Joel McHale comedy “Community” as well as Amy Poehler’s “Parks and Recreation” have received full-season pick-ups. I’m not really sure what’s up with “Parks” but the buzz on “Community” is huge and I will definitely check it out once I have time to watch more television. I’m sure fans of both shows are excited. Now if only NBC would cancel “The Jay Leno Show” they might be able to get above 4th place in the ratings.
