A man walked into the office of the eminent（杰出的，有名的） psychiatrist（精神病学家） Dr. Von Vermouth, and sat down to explain his problem.

"Well, you see, I've got this problem," the man continued. "I keep hallucinating（使产生幻觉）that I'm a dog. A large, white, hairy Pyrenees mountain dog. It's crazy. I don't know what to do!"

"A common canine（犬科的） complex," said the doctor soothingly（安慰地） . "Come over here and lie down on the couch."

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