Miss Sweetie Poo is a fictional character — a role played in the Ig Nobel Prize ceremony — but that role is played by a real eight-year-old girl. A blog commenter called ‘Shulamuth,’ familiar with Miss SP only from radio broadcasts, had understandably (given the rigorous selection process used to find each new Miss Sweetie Poo) not realized this. Shulamuth wrote:
