William Shatner, who gained worldwide fame and became a cultural icon for his portrayal of Captain James T. Kirk on the television series Star Trek and as attorney Denny Crane on the television drama Boston Legal, left a bold statement Wednesday night on The Tonight Show with Conan O'Brien. The 78-year-old actor graced the late night talk show to promote his book, Up Till Now: The Autobiography, as well as his latest comic effort, William Shatner Presents: The Tek War Chronicles, which arrives in stores on June 24. However, the interview was reduced to a farce when he stuck up his middle finger at O'Brien.
