A woman is driving along a country road when she accidently hits a rabbit. She immediately pulls over and gets out of the car, distraught.
A man is kind enough to see her distress and stops behind her. She explains what has happened and points to the twitching rabbit lying on the side of the road.
The man goes to the boot of his car and pulls out an aerosol can and sprays the rabbit liberally with it. To the woman's amazement, the animal springs to it's feet and bounds off into the hedge. Feeling much better, the woman continues her journey but is slightly surprised as she sees the rabbit running along side her car waving its paw at her. After two or three miles she stops again. The kindly man again stops behind her. The woman explains what she's seen and asks him what he used to revive the animal...
"Oh, that." he replies, showing her the can. "It's hare restorer with permanent wave..."

The first one was better
