Howard Stern spent the weekend in Los Angeles while promoting his wife’s book (‘Oh My Dog’), and Jimmy Kimmel decided to throw him a welcome party. Kimmel appeared on Stern today to discuss the party, and it was some of Stern’s most hilarious radio yet. My favorite detail involved an argument between John Stamos and Mark McGrath, where Stamos got angry with “musician” McGrath for his inability to play any songs for their shitty house band ensemble. Stern insists that Stamos’ anger was unfounded, because at least everyone could play the song ‘Louie Louie’. Stamos also gave both Kimmel and Stern shit for not inviting Don Rickles, who was peeved at both Kimmel and Stern for the oversight. Oh yeah – Jeff Probst left in a tizzy because of Stern’s inappropriate attempt to interview him about his new girlfriend at the party. Other celebrity guests included: Ben Stiller; Christine Taylor; Natalie Maines; Ryan Phillipe; Will Arnett; Amy Poehler; Christa Miller; Bill Lawrence; Bob Iger; Ashton Kutcher; and Demi Moore. I’ve got to become friends with Jimmy Kimmel in time for the next Howard Stern party. Knowing Stern though, he probably won’t return to Los Angeles for another 15 years. Watch Beth Stern promote her book on Kimmel below.
