I have a TIVO and DVR - still you do NOT distrub me during Supernatural. If you do I will pause it and explain the entire backstory. What happened to the the boys' Mother, what happened to Sam's girlfriend Jess, How the Lady in White in the pilot is actually from the Mexican Leaping Lady Legend ...... up until latest episode. I can also show you every episode to date (1st season on DVD, 2nd season on my TIVO). Needless to say I don't get interrupted during Supernatural. \
I have a history of similar behavior re: other science fiction type shows. So I as soon as I mention one - everyone knows do not call during this time.
Oh T'Mar of Vulcan I've gotten the "It is time to put up childish things" speach from Mom, and a couple of aunts one time each. My solution went something like this.
On Babylon 5 there was this character Deathwaker. She was a Mengula (SP) type character. She had preformed horrible experiments on living beings to develop this anti-aging drug. After the rest of her race was wiped out in a supernova, she offered this drug to the rest of the galacy. When asked by the hero why she was doing this, she replied that to make the drug the main ingrediant must be extracted from a living being. So for everyone who lived forever, another person must die. That type of referencing history and pushing ethical questions forward are what I enjoy about sci-fi. Now, I've never watched Everyone Loves Raymond - what is it that you enjoy about it?
(Note sci-fi loving cousins are cracking up in the corner) We don't get that speech anymore.
