Interview Question

So I was interviewing with a prominent university recently and one of the predictable questions came up--why do you want to work here in this position? It's something of a standard interview question but it made me think of a totally appropriate question to ask at the end of the interview--why would I want to work here in this position. I think it's a fair question, though be careful how you tone it, you certainly don't want it to come across as arrogant but in most instances it may lead to a better discussion.
