This is the term that TV Tropes uses to describe the AH phenomenon that involves placing historical people/celebrities in different occupations than OTL, more so for the sake of humour than anything. Here are a few examples of my own.
Kim Jong-il as the late CEO of Juche Electronics
Joseph Stalin as a mob boss that fled from Imperial Russia amidst the revolutionary chaos.
Joseph Goebbels as the founder and original head of advertising for Hakenkreutz Entertainment, main rival to Juche.
Rick Mercer as the President of Newfoundland
Don Cherry as Prime Minister of Canada
David Suzuki as Cherry's opposition, gaining support in the polls
Does the AH community have any other good examples?
