"Weeds" has been known for its envelope-pushing and sometimes sexy promotions, often featuring show centerpiece Mary-Louise Parker.

The latest promo, however, stars Kevin Nealon (who plays Doug Wilson) making a campaign speech, using a poster and catchphrase that seem pretty familiar.

An all-new season of "Weeds" premieres Monday June 8th at 10 PM ET/PT.

NBC set a record that nobody wants to set for TV viewership last week. For the entire week, the network averaged 4.4 million prime-time viewers, according to Nielsen Media Research.

While it's not the smallest ever recorded by ABC, CBS, NBC or Fox, it's certainly the smallest in a week outside of the expected summer lows of June, July, August or early September.

Last week's ratings were dominated by the season conclusions of TV's two most popular series, Fox's "American Idol" and ABC's "Dancing With the Stars." NBC didn't even bother to compete, airing shows like "Deal or No Deal" and "Most Outrageous Moments" instead.
