Joe went to a psychiatrist. "Doc," he said. "I´ve got trouble. Every time I get into bed, I´m sure that there´s somebody under it. I haven´t slept in a week. I´m going crazy." "Come to me three times a week and I´ll cure your fears." "How much do you charge?" "A hundred dollars per visit." Six months later, the doctor met Joe on the street. "Why didn´t you ever come to see me again"? "The Pizza Delivery Man cured me for $10. He told me to cut the legs off the bed!"
