Will my86 yr old father be offended by this?

I recently discovered this show a few days ago on Youtube and have found every clip from the show hilarious. I did notice an awful lot of very clever but fairly vulgar swearing. I'm getting the first season of DVD and wonder if my 86 yr old father can watch it with me. We both absolutely loved The West Wing and Madam Secretary, but I worry he won't go for it if it is mostly swearing with little story.
