My brother used to believe that potatoes were poisonous and if he found one in his room, it was a sure sign that his his room was haunted. My other brother pretended to be a doctor and diagnosed the patient with a rare case of 'potatophobia' which had to be treated immediately with a series of antidotes involving the potatophobic brother tidying the doctor's room for over a month. He was so scared out of his wits he agreed to do it. I used to put potatoes in his room just to see him shriek. I highly regret it now.
