A blonde, a redhead, and a brunette go to this fancy restaurant in Paris.
In the corner, they see a beautiful mirror. The manager says to them, "If you look at your reflection in the mirror and say something that is true, then you are granted one wish. But if you tell a lie, you disappear." The brunette wants to try so she walks up to the mirror and says, "I think that I am the most beautiful woman in the world!" She disappears. Then the redhead walks up to the mirror and says, "I think that I am the smartest woman in the world." And she disappears as well. Then the blonde walks up to the mirror, says "I think--" and disappears.
