A brunette, a redhead, and a blonde escape a burning building by climbing to the roof. Firemen are on the street below, holding a blanket for them to jump in. The firemen yell to the brunette, "Jump! Jump! It's your only chance to survive!"

The brunette jumps and SWISH! The firemen yank the blanket away. The brunette slams into the sidewalk like a tomato.

"Come on! Jump! You gotta jump." say the firemen to the Redhead. "Oh no! You are going to pull the blanket away!" says the Redhead.

"No! It's brunettes that we can't stand. We're Okay with Redheads." repied the firemen.

"Okay." said the redhead, and she jumped. SWISH! The firemen yanked the blanket away, and the lady was flattened on the pavement like a pancake.

Finally, the blonde stepped to the edge of the roof. Again, the firemen yelled, "Jump! You have to jump!"

"No way! You're just gonna pull the blanket away." yelled the blonde. "No! Really! You have to jump. We won't pull the blanket away," answered the firemen.

"Look," the blonde said. "Nothing you say is gonna convince me that you're not gonna pull the blanket away. So what I want you to do is put the blanket down, and back away from it."
