He voice of Rob Paulsen
The wisest man appears only in the Potion Making mini-game if the player makes the Wisdom potion. Upon appearing, the wisest man claims that the wisest man is he who understands that he understands nothing. Sam questions how can he understand if he understands nothing, but the wisest man claims he is now beginning to understand before disappearing.
