I never considered myself a Shatner fan. I have always been a "Captain
Kirk" fan, a "Spock fan", and (primarily) a Star Trek fan.

When Shatner did his "Get a life" bit, I did not think of it as aimed at
Star Trek fans. I assumed it was pointed at SHATNERHOLICS.

The fans parodied were Shatner-stalkers, not typical Trek fans.

I laughed, primarily because I wasn't laughing at myself. I was
laughing at people who were not like me. People who can't distinguish
between the actor and the role he plays are not like me.
