A few minutes ago, we had a few guys come to our door looking to trade something. Their goal was to start with an object and see if they could get the thing they were actually looking for.
Our dorm got a lovely huge canister of hot chocolote, which was not full, and we gave them a juicebox, 'an excellent source of vitimin C'. I wish them luck with their quest. Although I am not entirely sure what it is they were going for..
