What's the difference between a psychiatrist and a psychologist?

If you say, 'I hate my mother', a psychiatrist will ask, "Why do you say that?"

Whereas a psychologist will say, "Thank you for sharing that with us."

A man goes to a doctor. He says he is depressed. He says life seems harsh and cruel. He says he feels all alone in a threatening world, where what lies ahead is vague and uncertain.

The doctor says the treatment is simple. The great clown Terrifini is in town tonight. Go and see him. That should pick you up.

The man bursts into tears,"But doctor... I am Terrifini!"

An engineer and a psychiatrist meet up for their 20th college reunion.

The engineer says, "I'm surprised to see you still looking so young. I'd have thought listening to people's problems all day would have given you a mass of wrinkles."

The psychiatrist says, "You think we listen?"

In a psychiatrist's waiting room two patients are having a conversation. One says to the other, "Why are you here?"

The second answers, "I'm Napoleon, so the doctor told me to come here."

The first is curious and asks, "How do you know that you're Napoleon?"

The second responds, "God told me I was."

At this point, a patient on the other side of the room shouts, "NO I DIDN'T!"
