NEW YORK, NEW YORK (AP) Howard Stern's much-ballyhooed birthday show seemed like it had promise in the first hour. Despite the appearance of geriatric guests like Larry King and Barbara Walters, who came on first because curfew at the retirement home is 6 PM, the event was sill energized by jokes at Beth Stern's expense in what proved to be a half-hearted roast, and by surprising appearances with guests like Gov. Christie and Robert Downey, Jr. The energy of the first hour fell faster than Jim Florentine's cock the first time he saw ROQ naked.What little energy remained scattered like a fart in a hurricane after a tedious interview with David Letterman that seemed to last fifteen eternities, and left a drunk and bored crowd restless. Other pathetic stabs at humor fell flat. One song parody by Sarah Silverman offered promise, but the show eventually devolved into a sad eulogy punctuated with b-celebrity appearances and multiple costume changes by Stern's wife. A noticeably drunken Robin Quivers gave a rambling final tribute after Stern himself gave a long, rambling, boring interview with Dave Grohl. A final performance by Steven Tyler solidified Howard Stern's popularity with listeners aged 50-95, and proved he truly is still "KING OF ALL MEDIA." Ex-sidekick Artie Lange did not make an appearance.
