The jokes need to be funny of course, not just sexist remarks. You also have to know to whom you can say what. My close friends at work can be very brutal, and I return the favor ;). But you cannot do that to casual colleagues, or people you know that don't like such things. My best friend is 2m tall, so I also know all those jokes. But that doesn't stop us from annoying him now and then :D.
