Black Jew vs. White Jew

Okay, so this joke is playing on some pretty messed up stereotypes. It's saying the difference between a black Jew and a white Jew is that the black Jew is in the back of the oven, which is a dark reference to the Holocaust. People like you probably think it is funny to make fun of groups of people. You are a garbage person. I can tell just by looking at you (through the screen).
