14 yr old Roman Emperor Elagabalus is the inventor of the Whoopee Cushion

The Roman Emperor Elagabalus was known to employ a prototype of whoopee cushions at dinner parties,[1][2] although the modern version was re-invented in the 1920s by the JEM Rubber Co. of Toronto, Canada, by employees who were experimenting with scrap sheets of rubber.[3] The owner of the company approached Samuel Sorenson Adams, the inventor of numerous practical jokes and owner of S.S. Adams Co., with the newly invented item. Adams said that the item was "too vulgar" and would never sell. JEM Rubber offered the idea to the Johnson Smith Company which sold it with great success. S.S. Adams Co. later released its own version, but called it the "Razzberry Cushion."[3] @Curionic
