"A Brunette, a Redhead, and a Blonde..." joke

escape a burning
building by climbing to the roof. The Firemen are
on the street below, holding a blanket for them to
jump into.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."C'mon! Jump! You gotta jump!' say the firemen to
the Redhead."Oh no! You're gonna pull the blanket away!" says
the Redhead."No! It's Brunettes we can't stand! We're OK with
Redheads!""OK" says the Redhead, and she jumps. SWISH! The
firemen yank the blanket away, and the lady is
flattened on the pavement like a pancake.Finally, the Blonde steps to the edge of the roof.
Again, the firemen yell "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!""Look," the Blonde says, "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..."
