at a meating in a synagogue, Yossef asks the rabbi: "rabbi, why do people hate us so much?"
the rabbi says "that's an interesting question. how about we all talk about it tomorrow over some vodka. each one of you should bring a bottle so we can mix it in a big pot and drink, and discuss, and the answer will be clear."
Yossef went home and thought to himself "if everyone else is going to bring a bottle of vodka, if i bring a bottle of water no one will notice the difference."
and water was what he brought.
the rabbi poured all the vodka together in one pot, and started mixing it.
Yossef got anxious - "well, rabbi, what is the answer to my question? why do people hate us so much?"
the rabbi filled a cup and said "drink this Yossef"
yossef did and said "but this is water!"
and the rabbi said "and this is why the people hate us"
