A blond, a brunet, and a redhead are on top of a burning building, and so the fire fighters bring a net.
they yell to the blond, jump! She jumps, they move the net. they yell to the brunet, jump! she says oh no! I saw what you did to my friend! they yell, we like brunets! so she jumps they move she dies. So now the redhead is told to jump. she replies I saw what you did to them. they reply we promise we won't move we love redheads! she says, just drop the net and move 20 feet back.
