But, do you remember when Pluto was Yuggoth?
I always have fun telling my kids about the future when I would hold my grandchildren on my knee (my artificial knee, btw) and tell them about how when I was in college there was no such thing as the internet.
"That was way back '85." I'd say. They would stare wide-eyed in amazement.
"You mean 1985, Grandpa?"
"That's right, WAY back in the dark ages of the TWENTIETH century. We thought Pluto was a planet, Michael Jackson was a human, oil was for burning, and computers weren't things surgically inplanted into your skulls, no sir."
