Once upon a time, long, long, loooooooooooong ago, William Shatner considered himself to be a serious actor. Then came Star Trek and ruined that notion for him. It took him several decades to realize that his entire career was basically one big joke, but once he did, he just sorta rolled with it, and every single thing that he did became utterly hilarious. Nothing really changed outwardly, but you could tell that once he just accepted the fact that he was the world's biggest joke, he was having fun. Then you could look back on some of the things he'd done and see that he'd really been joking with us for a very long time.
