You Don't Know Jack

All 10 episodes have a “Wrong Answer of the Day” (henceforth referred to as WAOTD) question. If you correctly identify and choose the WAOTD as your answer, a prize is obtained. Once all 10 prizes are obtained (1 per episode), the trophy will unlock. See this post for the Jack Pack 4 WAOTDs. You'll know you've collected the prize if a present icon appears next to that particular episode.
