I was feeling a little out of it last night, so I think I might have missed any puns that my church history teacher threw out there. I am, however, looking forward to the middle ages because I think the term "flying buttress" deserves several pun mentions.
There was one little interchange that made me laugh, though. Our professor was pointing out that Ireneaus (I totally butchered the spelling there, I think... point is, he is a good guy) made an argument against the gnostics (the bad guys) that was essentially the same as the one the Catholics made against Martin Luther. This upset many people in the class (I'm sure this was on purpose, as the professor was trying to get people to think through the church's and Luther's predicament).
One student said, "Martin Luther was smarter than the average bear."
To which my professor replied, "See, I don't get that. Because bears aren't very smart."
