"The Psychiatrists" joke

"OK," said the psychiatrist, "let's try some tests. I'll draw something, and you say what it reminds you of."
He draws a house, and the patient says, "Sex."
He draws a square, and the patient says, "Sex."
He draws a circle, and the patient says, "Sex."
He draws a trangle, and the patient says, "Sex."
He draws a diamond, and the patient says, "Sex."
"I see; it seems to me," says the trick-cyclist,"you have a fixation with sex."
"Me? Who's drawing all these dirty pictures?"
A man is referred to a psychiatrist because he imagines himself to be a pet dog.
"All right, lie on the couch," says the doctor.
"Sorry, I'm not allowed on the furniture!"
