A Brainiac Calls Me Goofy

I'll take "Quiz Show Hosts" for $100, please.
A.) This quiz show host said he spent more time
      with Ken Jennings than with his wife.
Q.) Who is Alex Trebek?

You remember Ken Jennings, right? He's the former software engineer whose fifteen minutes of fame stretched to 74 days, the longest winning streak on the long-running television quiz show, Jeopardy!

Jennings wrote about Jeopardy! and trivia buffs in general in a book titled, "Brainiac". I won't say how the lead Brainiac himself has come to call me goofy (if not me, at least my hobbies), because that would require me to go into all sorts of detail defending myself, after which many readers are likely going to nod their heads and say something like, "Yeah, Jennings is right. That's goofy." So my best strategy is to lie low. All I'll say is that it has something to do with a new book Jennings is writing that has a chapter about games using a technology whose acronym is spelled S-P-G backwards. Buy the book. Unless it's goofy. ;-)
