I think I have a good sense of humor. I am a Christian, so maybe I’m impaired, but what was funny about the joke? It doesn’t even flow right when you read it.
The joke is not funny. In the same breath Bozell is saying that Christians do have a sense of humor, but that the joke is offensive. If you really had a sense of humor you wouldn’t take the time to write an indignant article about an unfunny joke.
