• "All Grown Up & Sexy" birthday party for Mona Scott Young. The Grand, 41 E. 58th St., nr. Madison Ave., 9:30 p.m. Ms. SexyGrown is an exec for the hip-hop management outfit Violator. Expected guests include Missy Elliot, Wyclef Jean, Lyor Cohen, LL Cool J, Busta Rhymes, Queen Latifah, Q-Tip, Ice-T, and The Wire's Jamie Hector, a.k.a. Marlo Stanfield. We're not going, because Marlo offed a favorite character of ours last season and things could get heated if we saw him. Also, we weren't invited.
• Reno 911 screening. Tribeca Cinemas, 54 Varick St., nr. Canal St., 7 p.m. Followed by cocktails with the cast, which includes the show's sheriff's-department regulars The State vets Tom Lennon, Ben Garant, and Kerri Kenney among them plus alt-comedy stalwarts including Paul Rudd and Patton Oswalt. Michael Ian Black, Michael Showalter, and David Wain make cameos. A rare chance to see most of the minds behind "I Want to Dip My Balls in It" in one place.
• "An Exclusive Smoking Event." Salon Nine, 32 Watts St., nr. Sixth Ave., 7 p.m. Sponsored by ThreeAsFour and Paper magazine. ThreeAsFour are the members of the AsFour fashion design team who didn't quit to scream at the staff of Sway and attack people with bags of bottles.
