Former Doobie Brothers star MICHAEL MCDONALD has hit back at actor Paul Rudd for making fun of him in the hit comedy The 40-Year-Old Virgin. In the film, Rudd's character works at an electronics store and is on the verge of a nervous breakdown after watching a video of MCDonald in concert on every TV in the store for two solid years. Rudd's character STEVE says in the film, "If I have to hear YAH MO B THERE one more time, I'm going to 'Yah Mo' burn this place to the ground!" But MCDonald got the last laugh at a concert at the Seminole Hard Rock Hotel + Casino in Florida last week (ends13AUG06), according to Page Six. As he got ready to belt out AIN'T NO MOUNTAIN HIGH ENOUGH, he told the crowd, "This one's for Paul Rudd!"
