Bill went to a psychiatrist. "Doc," he said, "I've got big trouble and I'm terrified at night. Every time I get into bed, I think there's somebody under it. So I get under the bed and then I think there's somebody on top of it. Then I get on top and think there's someone under. Under, top, under, top.... You gotta help me Doc, I'm going crazy!"
"No problem Bill, just put yourself in my hands," said the psychiatrist. "Come to me three times a week for two years, and I'll cure all your fears."
"How much do you charge?"
"A hundred dollars per visit," he replied.
"Wow, that much Doc? I'l have to think about it," said Bill.
Six months later the psychologist met Bill on the street. "Why didn't you ever come to see me again?" asked the psychiatrist.
"For a hundred buck's a visit? I couldn't afford that Doc! A bartender cured me for just ten dollars."
"Ten dollars, how did he do that?" asked the psychologist.
"He told me to cut the legs off the bed!" replied Bill.
