FunnyorDie.com has taken celebrity stunt casting in web videos to a whole new level with this Ron Howard(!)-directed short featuring every major Saturday Night Live alum who did a presidential impression on the show, from Chevy Chase (Gerald Ford) to Fred Armisen (Barack Obama). To replace the late, great Phil Hartman (Ronald Reagan), the production had to settle for a former road comic and Fox sketch show performer named Jim Carrey. Rounding out the cast: Will Ferrell, Darrell Hammond, Dana Carvey, Dan Aykroyd and Maya Rudolph as Michelle Obama (the sketch was written by an equally impressive roster of SNL and Simpsons alums: Al Jean, Adam McKay, Tom Gammill, Max Pross, Dan Greaney & Michael Price). Those names alone will behoove you to watch this, but they probably also make you a little skeptical that this could live up to its pedigree and actually be funny. Well, against all odds, it is. Now we wait for the sequel, in which Terry Sweeney leads the illustrious roster of SNL first ladies.
