Donald Trump decided that he doesn't want to attend intelligence briefings anymore. Coincidentally, he took notice how the Jews always have the inside scoop before anyone. So he consulted his cabinet of advisors how the Jews always were the first to know everything. And after much research by the intelligence community, the findings were very peculiar to say the least. ""Mr. President, we've found that any time a Jew greets another, they always start with a secret code: *vus machter reb yid*. That's Yiddish for 'what's new my fellow Jew?' - and then once you say that, they know you're Jewish and they trust you with all the inside info and the latest scoop. That's literally how the Jews know everything every time."" Trump looks at his advisors, and says ""Wow that's genius. Granted, I've come up with better codes than that but I'll give credit where credit is due! I'm gonna try this out, dress me up as a Jew!"" His whole cabinet proceeded to dress Donald Trump as a Hassidic Jew, the whole nine yards. He looked EXACTLY like a Hassidic Jew, you couldn't tell the difference, it was that good! The very next day, Trump went to Brooklyn which happens to have the highest concentration of Hassidic Jews in the US. He figures that the info he'll get there will be most current and up to date than anywhere else. All inconspicuous, he walks up to the first Hassidic Jew he sees and says ""vus machter reb yid?"". The Hassidic Jew answers ""Not much actually, but I heard Donald Trump is coming to town!""
