Promoting his gig as new host of “The Tonight Show,”Conan O’Brienstopped at WTHR (Channel 13) on Monday to film a few television spots.

O’Brien, who will take over the longtime NBC show’s reins June 1, joked with nearly everyone he encountered at the TV station Monday, including a makeup artist who used an airbrush to spruce him up before filming began.

“Everybody’s doing it,” he said, after noting that he is new to the technique. “They started in auto body shops.”

O’Brien, who spent the night at the Conrad Indianapolis, said he wanted to see the Slippery Noodle Inn but figured he wouldn’t have time before heading to St. Louis, the next city on his schedule.

“When you’re taking over ‘The Tonight Show,’ you’ve got to go to the heartland,” he said. “It’s polite to go and introduce yourself to people.”

Even if he didn’t make it to the Noodle, O’Brien said he got a look at it on his way into the city and said it has more neon in its windows than in any others he has seen.

If O’Brien had made it to the blues bar and restaurant, he supposed he’d “have way too much to drink, and then I’d jump in the White River.”

He also remembered a couple of other experiences with Indianapolis and Hoosiers, including the last time he visited the city and Hoosier band Margot&the Nuclear So and So’s, which appeared on his former late-night show in November.

“I rode around the track at the Brickyard in a minivan,” said O’Brien, who later added that his family car is a minivan and that women think it sexy. “I think I may have gotten to speeds as high as 62 miles an hour. Still, I wet myself.”

As for Margot: “Great band. . . . They were good.”
