A: Palpoutine.
   
     
Wikipedia: Poutine
Poutine (/puːˈtiːn/; Quebec French: [put͡sɪn]) is a dish originating from the Canadian province of Quebec consisting of French fries and cheese curds topped with a brown gravy. The dish emerged in the late 1950s in the Centre-du-Québec area and has long been associated with the cuisine of Quebec. For many years it was negatively perceived and mocked, and even used as a means of stigmatization against Quebec society. However, since the mid-2000s poutine has been celebrated as a symbol of Québécois cultural pride, and its rise in prominence led to popularity outside the province, especially in central Canada and the northeast United States. Annual poutine celebrations occur in Montreal, Quebec City, and Drummondville, as well as Toronto, Ottawa, Chicago, and Manchester, New Hampshire. Today it is often identified as quintessential Canadian food and has been called “Canada’s national dish”, though some have commented that this labelling represents misappropriation of Québécois culture.
     
Wikipedia: Palpatine
Sheev Palpatine, also known as Darth Sidious and The Emperor, is a fictional character and one of the primary antagonists of the Star Wars franchise, mainly portrayed by Ian McDiarmid. In the original trilogy, he is depicted as the aged, pale-faced and cloaked Emperor of the Galactic Empire and the master of Darth Vader. In the prequel trilogy, he is portrayed as a charismatic Senator from Naboo who uses deception and political manipulation to rise to the position of Supreme Chancellor of the Galactic Republic, and then reorganizes the Republic into the Galactic Empire, with himself as Emperor.
 
Though outwardly appearing to be a well-intentioned public servant and supporter of democracy prior to becoming Emperor, he is actually Darth Sidious, the Dark Lord of the Sith – a cult of practitioners of the dark side of the Force previously thought to have been extinct for a millennium in the Star Wars galaxy.
