A blonde, a brunette and a redhead were walking together. Along came a genie. The genie says,”Tell me something true about yourself and I will give you one wish. But if you tell a lie, I will make you disappear.”
So, the brunette says,”I think I’m pretty.” And she disapears. The redhead says,”I think I’m smart.” And she disappears.
The blonde says,”I think” … and she disappears!!
