The Saudis have unlimited cash, so my guess is his tuition was "well paid" in advance (so the college would overlook "stuff" in case he failed or never showed up). My guess is he's talking about his wife's loans? Why would he owe anything as a foreign exchange student sent here by the very, very rich Saudis?
Exactly! Show us the college tuition "loans" you AND Moochelle both had and paid off...yourselves.
