So a bunch of us reporters were sitting in the Motor City Hotel and Casino waiting for Tony Stewart to arrive for a Michigan International Speedway promotion when all of a sudden, in walked bad-boy rocker Kid Rock.

Rock, who was at the hotel for a meeting, saw signs directing the media to the Tony Stewart news conference, and he followed them so he could see his good buddy, bad-boy racer Tony Stewart. The two have been friends for about seven years.

Stewart, upon seeing Rock, jokingly called out: "Don't you have a job?"

Rock, leaning in, then said: "He's the greatest guy I ever met ... Didn't he say the same about me?"

Actually, he sort of did. Stewart went on and on about Rock's talent as a musician, calling him, "one of the most talented artists I've ever met. If he were as talented a race car driver as he is a musician, he would have no problem making the Chase."

High praise, indeed.

Among some of the other highlights of the day, Stewart, when asked if he thinks he'll ever marry, said: "You know, that's the one part of my life I haven't figured out yet. I'm 36 now and I think I might actually like to see the same person at the end of the day."

He also mentioned his idea of getting one tattoo. Stewart said he isn't certain what it might look like, but he would like for it to encompass three things: his love for racing, his old-school way and his sense of humor.

Huh? His sense of humor?

"Well, I think I'm funny," Stewart said.

• Andy Roddick, on the defensive this week when asked about the popularity of the Davis Cup, reacted when one reporter pointed out tennis often is buried in sports sections and during sportscasts behind NASCAR and other sports.

"It's a little disappointing we're behind a sport that you turn left for four hours," Roddick said. "I mean, around the world [tennis] is probably just behind soccer as far as the biggest sport in the world."

Sprint Cup series driver Michael Waltrip said he doesn't care what Roddick thinks about racing.

"I played tennis in high school, and that wasn't that hard, either," Waltrip said. "I wanted something more challenging, so I became a race car driver."
