If you need a pointer or two, here's Jim Carrey's take.
But one comedian, Michael Terry, completely nails the Olbermann impression in the video after the jump. In it, he doesn't attempt to ape the entire show; he just makes a Special Comment complaining about how he got cheated on his Subway sandwich. "Double meat, sir, as any Ritalin-addled eight-year old will tell you, means twice the amount of meat." It's hilarious, and it puts Affleck's impression to shame.
Following the strong ratings figures for Tyler Perry's House of Payne, which received that order for 10,000 episodes right off the bat, give or take 9,000, and the solid premiere of The Bill Engvall Show, TBS struck comedy gold again with Frank Caliendo's Frank TV. The late-night sketch/impression show scored an impressive 2.9 million viewers, according to Variety, with a not-surprising-at-all 64% of those in the coveted 18-49 demographic.
Caliendo, whose impressions include George W. Bush, the entire main cast of Seinfeld, Robin Williams and his signature John Madden, plays virtually every character on the show. His Bush is so dead-on, if the strike continues, he can just stand their and make Bush's classic expressions for thirty minutes. His half-smiles, smirks and squinchy eyebrows are enough to bring audiences to tears.
