What's the difference between an electric car and a jew? That's right, you don't gas an electric car.
Do you have something against Jews?
Well I just mean that being a jew is not really a good thing and it might be better for them to just disappear. People should also do something about the jewish problem.
Being a Jew isn't a bad thing, either. Joking about the genocide of a group of people really isn't funny and I think you should think carefully about your joke material.
