To restore a dead bunny
A traveling salesman was driving down a country road when a rabbit ran in front of his car and he hit it. The proverbial farmer was sitting on the fence watching.
The salesman gets out of his car and opens the trunk. He then removes an aerosol can and sprays the contents on the dead rabbit. The next thing you know the rabbit gets up and hops about 20 ft. down the road, turns and waves to the salesman, goes another 20 ft. and waves to the salesman. The salesman looks at the farmer and says "he'll be okay now." The salesman gets into his car and leaves.
The farmer wondering what's going on walks over to the ditch where the salesman threw the can, picks it up and read the label which said: FOR HARE RESTORATION AND PERMANENT WAVE.
