Anyone who watched MADtv will remember Frank Caliendo. He joined the cast in 2001 and instantly shot to stardom after people realized what a master of impressions he was. His 5-year run on the show saw him play many characters, but nothing ever topped his John Madden impression.
In 2015, Caliendo signed a contract with ESPN, bringing him on to impersonate sports figures during Sunday NFL Countdown.
Caliendo also got his very own, albeit short-lived, TV series called Frank TV which he described as "The Muppets meets SCTV, meets Saturday Night Live, meets the Simpsons."
We decided to round up some of Caliendo's best impressions, and we can barely tell the difference between him and the real thing!
