End Of Dr. Palmer

Dr. Palmer, geneticist, realized one day that of all the animals, no one had yet thought to sequence a dog's genome. He therefore gathered his team and immediately set to work.

Dr. Palmer quickly discovered there was something wrong with dog DNA. They didn't have any. Every dog he tested was composed of completely foreign protein sequences. Palmer concluded they had been planted here by an alien civilization to observe Earthlings.

End of Dr. Palmer.

Several years later, Dr. Robinson, geneticist, realized one morning that none of his colleagues in the field had ever bothered to sequence the dog's genome.
