"SNL," 1979-1980 and 1984-1985: Though he reportedly despised his time on "SNL," Shearer had a number of excellent impressions, including Mike Wallace, Rod Serling, Ronald Reagan and Tom Brokaw.
Shearer's face is probably best known from the comedy band Spinal Tap, but his voice is world famous. Today, he continues to voice Mr. Burns, Smithers, Ned Flanders, Kent Brockman and Principal Skinner (among many) on "The Simpsons." —XFINITY Entertainment Staff (Photo by Rick Diamond/Getty Images)
