Dogbert walks toward the Dog Doctor. The veterinarian says, "Hi, Dogbert. How are you?" Dogbert replies, "Not so good, Doc." Dogbert explains, "I have a bad case of 'happy tongue.'" The vet says, "Hmm . . . Is your tongue happy for any particular reason?" Dogbert replies, "No reason at all. I'm quite worried." The vet says, "I'm going to prescribe these tongue depressors. Use one every time your tongue gets too mirthful." Dogbert leaves the office humming. The doctor thinks, "I like that dog."
