A blonde a brunette and a redhead

Are all on top of a burning building. The firemen can't come up to save them so they stretch out a blanket below and tell them to jump.

The red head looks over the egde and says "I don't know, I'm scared"
The firemen reply "don't worry we love red heads we won't let you drop."
So she jumps and right before she hits the blanket they pull it out and she goes splat on the sidewalk

Horrified at what they just saw, the blonde and brunette don't know what to do.
The firemen call out to the brunette
"Jump down, jump down we'll save you, we don't like red heads but we love brunettes!"
So the brunette jumps and right before she hits, again they pull out the blanket and splat on the sidewalk.

The firemen stretch out the blanket and call out to the distressed blonde
"Jump down jump down we'll save you! We hate red heads and brunettes but we love blondes!"
The blonde thinks for a moment and yells back
"IM NOT FALLING FOR THAT! PUT THE BLANKET ON THE GROUND AND STEP AWAY!"
