My Three Sons S05E30 - Steve and the Computer

Steve is having nightmares and his vision of the future has a computer named Betsy join the family. It interferes with wedding plans when it selects different mates for Mike and Sally. Hoping to prove the computer wrong, Mike decides he will have Steve fill out a questionaire for his dad and his mother. His reasoning is that they will submit the two forms and the computer will pick someone else for their perfect match, thereby proving to Sally how wrong the computer can be. But lo and behold the computer mates Steve and Mike's mom.
