Your weekend Plan of Action.

Friday Justine Joli Signing and Happy Hour
Testosterone (and boners) will be high when Penthouse Pet Justine Joli and photographer Ellen Stagg tag-team Motor City tonight. They'll be signing the Living Proof magazine skateboard decks that feature Stagg's photograph of Joli's naked ass, while bartenders sling 2-for-1 drinks. Just do us a favor when you ask her to sign your "board" -- don't make it sound like a euphemism for something else. (Free, 7–10 p.m. at Motor City.)

Saturday "North Hollywood" Screening
In 2001, Judd Apatow was little more than some guy who used to be Adam Sandler's roommate. His cult classic TV show "Freaks and Geeks" lasted barely one season and he was back at square one. His first foray out of the woods was "North Hollywood," a 22-minute pilot that starred big comedy hitters, like Amy Poehler, Jason Segel, Colin Hanks and Judge Reinhold. Eventually, Apatow would move on to huge paydays for movies in which Seth Rogen is the handsome male lead; nine years ago, however, no one wanted "North Hollywood." 92YTribeca comes to the rescue with a copy of the never-aired show. ($12, 9:30 p.m. at 92YTribeca.)

Sunday "Mad Men" Viewing Party
Don Draper got divorced. Betty Draper ran off with another man. Christina Hendricks married that dopey dude from "500 Days of Summer." Last season's "Mad Men" was an obvious downer, both on- and off-screen, but Season 4 promises a huge jolt of life for AMC's award-winning series. The only proper way to celebrate (besides spending the full hour under the desk with the receptionist) is to head to The Oak Bar up on swanky Central Park South for the highball cocktails and burlesque revue. (Sure, they may get around to watching the show, but you might want to DVR it just in case.) Dancing girls The Sophisticates kick off the show, with accompanying DJ Bastard Keith, whose moniker that might have raised a few eyebrows at an actual Sterling Cooper affair. ($15, 10 p.m. at Oak Bar.)
