I've never seen an episode of The Simpsons in my life but managed to score 11 just by guessing. Still didn't rack up any points, though. I tried gardener for Willie's job - so close, and the letter would still have worked.
i think it does this because when you take a quiz untimed, it won't update your score on the systems it uses to calculate points, but it will save that you scored that - ie some places have your best timed score, and some include untimed scores. however i'm not sure and have often wondered so it would be good if qm or someone who knows could confirm?
"Your high score is 26"
????
I can't believe how poorly I did; minus 11. I haven't watched TV in probably 10 years.
