Click to view Boomp3.com America has spent much of the summer of 2008 falling in love all over again with Robert Downey Jr. It wasn't only his acting prowess, mind you, but also his fantastic facial hair. However, the changing of the seasons means that it's time for him to shave off his beloved goofy mustache. The Iron Man debuted his (mostly) clean shaven look at the UK premiere for Tropic Thunder . Downey Jr. said, “I think the mustache had ran its course. It tickled my wife when we kissed. It was an excellent flavor saver. For a while, it smelled like a Robeks and I loved it. Now, I have to go to work and become an adult all over again.” [Photo Credit: Getty Images ] *A Call To The Bullpen is a work of fiction.
