Give Joe Biden a high five. The Vice President of the United States turns 67 today. (Let's all hope he gets through the day without any more accidents.) The oldest member of Congress, Sen. Robert Byrd of West Virginia, turns 92 today. Former U.S. ambassador to the U.N. John Bolton is 61. Mike D of the Beastie Boys turns 44. Joel McHale of The Soup and Community is turning 38. Pat Kiernan of NY1 is turning 41. Actress Sean Young is 50. Bo Derek turns 53. Author Don DeLillo is turning 73. TV anchor Judy Woodruff turns 63. Avant-garde performer Meredith Monk is 67. Tween star Cody Linley turns 20. Former Eagles member Joe Walsh is turning 62. And Mark Gastineau, the retired football star and father of Brittny, is 53. Below: A few folks celebrating birthdays this weekend, including Scarlett Johansson and Tina Brown.

• Publishing heir Robert Ziff has dropped the price of his three-bedroom condo at the Trump International. The 41st-floor pad, which Ziff picked up for $5 million back in 2001 before moving to 720 Park a couple of years later, first went on the market for $13 million in July 2008. It's now listed for $11.5 million. [Cityfile, Sotheby's]
• Selling the triplex penthouse at 895 Park that once belonged to the late producer Charles Evans hasn't been easy. The co-op's board, led by real estate developer Dan Brodsky, has turned down an offer for the third time. Now that the unidentified financier's $14 million bid has been rejected, the apartment is now back on the market for $15.5 million. [NYO, Stribling, previously]
• KKR partner Alexander Navab has put his four-bedroom apartment at the River House on the market for $24.5 million. The 4,806-square-foot co-op comes with terrace, private elevator, and river views. [Real Deal, Sotheby's]
• Real estate developer Andrew Heiberger has sliced 12 percent off the asking price of his townhouse at 161 East 63rd Street, which he bought for $8.15 million in 2004 and put on the market for $16.85 million in February. The six-story mansion is now listed for $14.85 million. [Real Deal, Sotheby's]

Tina Brown's party earlier this week to celebrate the launch of her new site, The Daily Beast, could have just as easily served as an early birthday bash: The famed editor turns 55 today. Indie film powerhouse Christine Vachon is turning 46. Bjork is 43. Goldie Hawn is 63. Publicist Mara Buxbaum is 41. Retired football player Michael Strahan is celebrating his 37th. Actress Cherry Jones is 52. Real estate developer Daniel Brodsky is 44. Norman Siegel, civil rights lawyer and perennial candidate for public office, is 65. Congresswoman Yvette Clark is 44. Nicollette Sheridan is 45. And actress Marlo Thomas is 71. Weekend birthdays after the jump.

895 Park Avenue, the Art Deco co-op on the southeast corner of 79th Street, isn't quite as famous as some other Park Avenue co-ops a few blocks to the south, but it easily rivals (or exceeds them) in terms of grandeur. Roughly two-thirds of the building consists of sprawling 14 and 15-room duplexes, the kind of places that have as many fireplaces as you have windows and where even secondary bedrooms have their own dressing rooms. (That still wasn't quite enough for the late socialite Nan Kempner, who lived at 895 Park for nearly five decades: She reportedly turned several of her extra bedrooms over to her clothes.) Naturally, such a palatial building throws off plenty of campaign money. Here is how some 895 Park Avenue residents have placed their bets in this year's presidential race.

Daniel Brodsky is managing partner of the Brodsky Organization, a real estate development and property management firm.
