Time to get a sense of humour people!
In the news today, the guy who has told jokes like, "If men fall asleep directly after sex, why is it so hard to catch a rapist?" and, "Say what you will about the Nazis; but, they did manage to conduct a lot of medical research without hurting any animals." told a joke that made people (including me) laugh which was also offensive.
The best thing that people can do when they're stereotyped as not having a sense of humor is to either develop a sense of humor or simply ignore jokes by people who are constantly pushing the envelope.
