On Friday, March 22, the one and only William Shatner celebrated his birthday. I won’t tell you his age because it just makes us all feel old. To celebrate the occasion, Hulu has done a wondrous thing: they’ve made every episode of Star Trek available to watch for free for a limited time. That’s right, every episode. You can jump between the Original Series and The Next Generation. You only have until April 1st though so clear your schedule and get to work.
