A veterinarian was also an amateur geneticist. One day, one of his experiments paid off. He successfully combined the DNA of a cantaloupe with that of a dog. The result was a small, round dog with orange-tinted fur. For many years, the dog was happy. But over time, he became lethargic and morose. The vet tried everything to cure the dog's depression. Eventually, he decided to take the dog to a pet psychiatrist. The psychiatrist told the veterinarian not to worry. The dog was just a little melon collie. *(Received from Stan Kegel)*
