"Wanna race, mister?" she asks, ringing her bell and twirling the elastic streamers on her handlebars.
"Sure," the man laughs. The light turns green and he floors the pedal. The car takes off like a shot and he leaves the little girl in the dust.
A few seconds later though, he sees something gaining on him in his mirror, fast. He just barely catches a glimpse of the little girl on her bike as she shoots past him. "She must be going 80 miles per hour!" he shouts, and shifts into a higher gear, pushing the car even faster.
He quickly blasts past her as if she were standing still. But again, just a few seconds later, she shoots past him, now doing over a hundred miles an hour on her little bike. Going so fast, sparks and smoke are streaming from her training wheels.
After another few seconds, he comes to a curve where he sees the little girl crashed in a heap on the side of the road. He pulls over and jumps out to see if she's okay. Miraculously she's survived. So he asks, "Why did you go so fast?"
Just as she falls unconscious, the little girl replies, "my streamers got caught on your mirror!"
