@@bigwillietheb many many years ago on HBO when I was a kid. at that time i had no idea who she was but years later after i saw the first ep of The Nanny i started to remember the VOICE! and i remembered her in that as well as This is Spinal Tap and Hollywood Knights. The voice that her HS acting teacher told her would never let her have a career is one of the defining attributes of her career lol goes to show ya never listen to the naysayers!
That's how I know I've gotten old, Spock is referring to Dr. Spock, an author, and psychiatrist who in the 1950s wrote books and childcare and love from a psychological standpoint. The first joke has nothing to do with Spock from star trek. It then becomes about star trek with the second joke, that's why it's funny.
