Rabbit Save
One day a man was driving down the road in a hot red convertable. He was driving 15 mph when a rabbit hopped in front of his car. As the man swerved the rabbit swerved also and was run over. The man got out of the car and started crying, upset that he'd killed the rabbit.
Just then a woman drives up and asks him what's wrong, when he tells her she says, "Oh I can fix that." She goes to her car, pulls out a can and sprays the rabbit with it.
It instantly comes alive and hops off, but every five feet it turns back to wave, before finally dissappearing into the forrest.
The guy is amazed and says, "How did you do that?" The woman just tosses him the can and drives off. The can says "Hair Spray: Guarenteed to bring your hair back to life and create a permanent wave."
