I taught LSAT which opens me up to the occasional question about it, then the usual joke about how they wish they wish they had me to teach them, ect. It is good for me, becuase I was somewhat of a split with a average UG gpa, and it gives me a way to work it in. I also open myself up to questions about religion b/c I studied religious studies in undergrad, and those questions are always a fine line to walk because you never know the interviewer's personal beliefs. I think the questions about that subject are more to confirm I am not some religious fanatic who will be swayed by personal beliefs (which is very far fromt he truth).
