Magic 8-ball, will I pass my computer class' final exam on Tuesday?
"Very doubtful."
And that actually means "yes" because you know this 8-ball. 
My Computer Exam got rescheduled to Thursday due to Instructor illness so:
Will I pass my computer class' exam on Thursday?
"Without a doubt."
Well, at least the 8-ball tells the truth some times, because I passed the exam Thursday.
Will my computer stop trolling me anytime soon?
