William Shatner Kept Stealing Toupees From the 'Star Trek' Set:
"A reporter once asked Gene Roddenberry, the creator of Star Trek, why
Captain Picard was bald. "Surely, they would have cured baldness by the 24th
century," the reporter commented, to which Roddenberry responded, "They
were too busy trying to find a cure for your face"… in the unauthorized
biography that I'm currently writing. In real life, though, the man actually said,
"In the 24th century, they wouldn't care," which is a beautiful sentiment that
gets to the very heart of Star Trek. Unfortunately for him, William Shatner was
born in the 20th century, so he very much cared about being bald, and he dealt
with it by stealing his official Captain Kirk toupees."
