I think this is from 1992 Computer bowl I was watching recently. Bill Gates was the quizzer along with the show host Stewart Cheifet. Sample the following tongue-in-cheek answers from respondent when neither of the team seemed to know the answers.

Bill Gates asks the question: "Since 1984, a contest has been held on Usenet for the most unreadable, bizzare but working C C program. What is the name of this contest?"
After ascertaining that nobody in his team or the other knows the answer, Jean Louis Gassee, Chairman and CEO, Be Inc. replies: Windows! :))

In the same episode, certain time is elapsed after the question above and a funny moment comes again. Theis time, Bill Gates asks: "This 1985 movie was about two nerdy teenagers who use a computer to conjure up a woman of their dreams. What is the name of the movie?"
Again, neither East coast nor West coast knows the answer. Seeing the silence, Mitchell Kertzman, Chairman and CEO, Powersoft Corp. responds brilliantly: Bill and Paul's excellent adventure! (Fashioned after Bill and Tedd's Excellent Adventure) :)

I am sure Bill Gates wouldn't have conducted any quizzes after that! Just kidding :) He actually accepted all these comments quite gracefully, smiling all the time.
