Psychiatrist's Best Friend

A man walked into the office of the eminent psychiatrist Dr. Heidberg, and sat down to explain his problem. "Doctor, doctor! I've got this problem," the man said. "I keep hallucinating that I'm a dog. It's crazy. I don't know what to do!"

"A common canine complex," said the doctor soothingly. "Relax. Come here and lie down on the couch."

"Oh no, Doctor," the man said nervously, "I'm not allowed up on the furniture."
