LOS ANGELES, California (CNN) -- One of Frank Caliendo's best impressions may be that of President Bush, but he says that his sendup has nothing to do with politics.
Frank Caliendo does impresssions of a host of politicians, sportscasters and entertainers.
"We're not hugely political," Caliendo says of his show, "Frank TV," which recently returned for its second season on TBS (11 p.m. ET/PT). "We hit the politics because it's in culture ... an extreme amount right now. After the election's over, we basically go back to our normal type of making fun of TV and movies and stuff."
Caliendo, perhaps the most famous impressionist since Rich Little, is an equal-opportunity political opportunist. He also does Republican John McCain and Democrat Al Gore, along with a host of sports figures (John Madden, Charles Barkley) and entertainers (Jack Nicholson, James Gandolfini, Sean Connery, Al Pacino and Robert De Niro).
Barkley, the NBA legend turned sportscaster, is a particular favorite, Caliendo tells CNN.

"The most fun that I have right now is Charles Barkley because I can walk around calling people knuckleheads and ... everybody just laughs. [It's] like, 'That guy's a knucklehead ... a terrible, horrible really bad knucklehead.' "
And what's the key to doing a good Bush? Being linguistically creative, he says.
"If you put 'ify' or 'icate' on anything, that's a Bushism," he says. " 'I gotta thinkify, I must brainificate.' "
TBS is a unit of Time Warner, as is CNN.
