A man walked into the office of the eminent psychiatrist Dr. Von
Vermouth, and sat down to explain his problem.
"Well, you see, I've got this problem," the man continued. "I
keep hallucinating 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 complex," said the doctor soothingly. "Come over
here and lie down on the couch."
"Oh no, Doctor. I'm not allowed up on the furniture."
