I don't think you have any business putting "humour" in quotes. If they sincerely meant it as humour, and I think they did. Then it is humour. Its ok that you disagree and don't like it but I would like to see you lighten up. That's why I told the snail joke.

BTW, I think I just found out that you are neither a snail nor a magazine sales man who is offended by profanity.
