Mike Rowe on running for office: Never say never, but I prefer the kind of dirt that washes off

"Somebody's Gotta Do It" premieres Wednesday at 9 p.m. on CNN.

(CNN) – With approval ratings of Congress at record lows, being a politician may be one of the dirtiest jobs out there.

CNN's "Somebody's Gotta Do It" host Mike Rowe has testified before Congress, urging the retraining of workers and the promotion of trade schools. Reviving America's workforce, Rowe advocates, requires skills that aren't necessarily obtained in a college classroom.

Asked if he would he would ever run for office, the former "Dirty Jobs" host  quipped: "I prefer the kind of dirt that washes off in the shower."

"I mean obviously never say never, but I'll say not without term limits, I wouldn't even imagine thinking about it," Rowe said.

"The 'Mike Rowe Foundation' is focused on trade schools and work ethic scholarships, and once a year I do go to the Capitol, I talk to Congress, I yell at them, and it's kind of fun," he said.
