When we had someone in for an interview, I'd often circle back and ask the office admin (that also covered reception) what she thought of them. It was pretty informative and eliminated a few candidates. I've seen someone give the advice of responding to crude sexist "jokes" by asking them to explain it then explain the explanation. Just keep insisting that you don't get it and don't understand why it's funny and see how deep you can get them to dig before they get it.
