King's Quest
Kings Quest is an alleged 'challenge' of allegedly murky origin that is allegedly well known among certain segments of the fraternity population. The challenge is simple: have sex in each of three campus locations.
1) The Butler stacks 2) The roof of Low 3) The tunnels
By one account, the pairing must be with a Barnard student, and some versions substitute the gym or swimming pool for the tunnels. Additional variations include having sex during Bacchanal weekend and completing each stage of the quest with a different companion.
