A man walked into the office of Dr. Seymour Epstein, a well known psychiatrist and sat down to explain his problem.
"Doctor Epstein, I've got this problem," the man said. "I keep thinking that I'm a dog. It's crazy. I don't know what to do!"
"A common canine complex," said Dr. Epstein soothingly. "Relax. Come here and lie down on the couch."
"Sorry Doc," the man said nervously, "I'm not allowed up on the furniture."
