Superman's Pal, Jimmy Olsen #32

Professor Potter accidentally slips Jimmy a \"Pinocchio Legend\" formula intended as a lie detector. It works, making Jimmy's nose grow - and grow and grow - whenever he tells a lie. He discovers \"telescopic smell\" and sniffs out a fire across town, then blows away a crook with a super sneeze. Lois, meanwhile, slips Clark the \"perfume\" to check if he's really Superman - and Clark's nose also grows!
