It is possible to be shockingly, blindingly funny without being offensive or saying things that stand a good chance of hurting feelings.
It also is way harder to do than being shockingly, blindingly funny while using every offensive technique, word and subject available.
If you are willing to settle for offensive and you want funny, read all of these comics (IDK). It is sort of like Saturday Morning Breakfast Cereal meets XKCD. Regularly pound on the desk, howl out loud funny, also likely to offend nearly everyone. You were warned.
