"I think he still has some good jokes in him, but right now he's doing some serious work," Klobuchar said.

His potential arrival has been buzzed about for months. Not only does Franken bring with him a filibuster-proof, 60-vote majority for the Democrats but also a catalog of comedic material and lively commentary as a radio host and writer.

Not that you would know it on Monday.

As cameras clicked rapidly in the background, Franken downplayed that 60th Democrat business.

"A lot has been made of this number 60," he said. "I'm not focused on that."

He listed education, health care and energy issues as areas he hoped to take on immediately.

Reid, never accused of being a master joke teller himself, played straight man to Franken's reformed funny-man. Like Franken, Reid downplayed the significance of 60 votes — and offered nothing resembling comic relief.

Reid spoke dryly about how much the Senate would not change despite its newest arrival. He glanced down, then up, down, then up at his audience. If he cared that he and his guest had disappointed a room full of style writers, reporters and TV camera crews, he did not let on.

Instead, Reid cited praise of Franken from former Republican Rep. Vin Weber of Minnesota as evidence of Franken's intellect and earnestness. He promised Franken was coming to Washington with no greater goal than to work hard for his constituents.

"I expect him to help deliver change," Reid said, adding later "We need more than just his presence to address these challenges."

Almost as quickly as Reid and Franken arrived, they were off, taking no questions, offering only a handful of smiles between them.

Aides said Franken would be in meetings much of Monday, including sessions with the staff of his new Senate office. Earlier Monday, workers installed Franken's new name plate in front of the office in the Senate's Hart Office Building vacated by Coleman.
