I searched AWAD and didn't find it already posted so here goes.

A man was driving late one night and caught in his headlights was a rabbit. The man tried to swerve to avoid it but the rabbit jumped too, and the man felt the thump. He stopped and got out, and there just in front of the car was the rabbit, dead. Being a wimp, sorry, a compassionate human being, the man started crying. Just then another car drove up, and stopped. The woman driver saw that the man was crying over the dead rabbit and said "Don't worry - I can fix that!" and reached into her handbag (purse in US?), took out an aerosol can, and sprayed the rabbit. After a few seconds the rabbit started moving, shook itself and started hopping down the road, stopping every few feet to turn and wave at them until it disappeared in the distance. "That was amazing!" said the man, "What was in the can?" The woman showed him the label and the man read "Revives Dead Hair, Adds Permanent Wave".
