This joke perfectly captures why as a Polish woman, I will never be a part of the Western world, if Gilbert Gottfried were Polish, he would tell such jokes.

 It's an explanation about the apparent beef with Rush fanbase, which I'm forgetting about now:

"There were three Polish men and one Polish woman. They went to a casting in Hollywood. The director, casting guy opened the door for them. He asked: 'What do you have to offer?' To this, they replied: 'We are a rock band, could you listen to our recordings?' The recordings were good, the foreigners praised them, claiming they could match the classics of rock. To this, the casting guy replied: 'That’s out, next please.' So the whole four began to show their acting talent for playing in dramas, comedies, etc. To this, the casting guy answered: 'Noooo, that’s out! Next please!' So they started circus tricks, including juggling, acrobatics, as well as animal training. To this, the casting guy answered again: 'No, that's out! Next please' The desperate and terrified crew began to cry bitter tears: 'NOOO, WE BEG YOU... WHY DO YOU HATE US SO MUCH?' To this, the casting guy replied: 'Because you’re from Poland and you were hurting my family,' the casting guy replied, specifically having no proof that the whole four and their famillies hurt his family. To this, the desperate four replied: 'IS THE BLOOD OF OUR ANCESTORS NOT ENOUGH FOR YOU??? Ukrainians sawed us with a saw, Germans put us in camps, smashed the skulls of infants, Russians sent us to Siberia, to the cold, Ukrainians applied 300 tortures over several years against us, including nails to the skull, Germans shot in the back of the head, Russians too, Germans suffocated us with gas, Russians lashed us, raped children, women, animals, smeared excrement everywhere at the faces of our ancestors, literally like monkeys, not to offend them, these barbarians, women, children, old people etc. suffered agonies, Oh Jesus...' To this, the casting guy replied: OH F*CK BUAHAHAHAHAHAHA, THAT IS THE FUNNIEST JOKE IN THE WORLD, BECOME COMEDIANS, YOU HAVE A PERMANENT JOB WITH ME! The Polish four left, took offense, and never returned..."
