Joe has been seeing a psychoanalyst for four years to treat his fear of monsters living under his bed. His progress was very poor, so one day he stops seeing the psychoanalyst and decides to try something different.
A few weeks later, the psychoanalyst meets Joe in the supermarket, and is surprised to find him looking well-rested, energetic, and cheerful.
“Doc!” Joe says, “It’s amazing! I’m cured!”
“That’s great news!” the psychoanalyst says. “How?”
“I went to see another doctor,” Joe says enthusiastically, “and he cured me in just ONE session!”
“Only one session?!” the psychoanalyst asks incredulously.
“Yeah,” continues Joe, “my new doctor is a behaviorist. He told me to cut the legs off of my bed.”
