Peter, a well known anti-Semite, walks into a bar and is about to order a drink when he sees a guy close by with kippa, tzitzis, and payos. He doesn't have to be an Einstein to know that this guy is Jewish. So Peter shouts over to the bartender so everyone can hear, "Drinks for everyone in here, bartender, but not for that guy over there," pointing to the Jewish guy.
Soon after the drinks have been handed out, Peter notices that the Jewish guy is smiling. This infuriates him and in a loud voice, he once again orders drinks for everyone except the Jewish guy. But as before, this does not seem to worry the Jewish guy who continues to smile. So he says to the barman, "What's the matter with that guy over there? I've ordered two rounds of drinks for everyone in the bar except that guy, and all he does is smile and look happy. Is something wrong with him or something?”
"No, he's absolutely normal," replies the barman. "He's the owner."
