(CBS/AP) The comic mechanics on NPR's "Car Talk" are calling it quits.

Brothers Tom and Ray Magliozzi said Friday they will stop making new episodes of their joke-filled auto advice show at the end of September, 25 years after "Car Talk" began in Boston. Repurposed versions of old shows will stay on National Public Radio indefinitely, however.

The show airs every Saturday morning and is NPR's most popular program.

"We've managed to avoid getting thrown off NPR for 25 years, giving tens of thousands of wrong answers and had a hell of a time every week talking to callers," Ray Magliozzi said. "The stuff in our archives still makes us laugh. So we figured, why keep slaving over a hot microphone?"

The duo will continue writing their "Dear Tom and Ray" column twice a week, NPR said.

"My brother has always been 'work-averse,' " says Ray, 63. "Now, apparently, even the one hour a week is killing him!"

"It's brutal!" adds Tom, 74.

The two men proved that public radio didn't have to be stuffy, said Doug Berman, executive producer of the show. "Car Talk" began as a local call-in show on Boston's BUR radio in 1977. It's now on 660 stations across the country, with some 3.3 million listeners a week.

"The guys are culturally right up there with Mark Twain and the Marx Brothers," Berman said. "They will stand the test of time. People will still be enjoying them years from now. They're that good."

The staff has stored and logged some 12,500 phone calls since the show began, rating them in order of their entertainment value, Berman said. They will take the best and use them for the repurposed shows. Berman said he figured there was about eight years' worth of strong material without the show having to repeat itself again.

In a goodbye message posted on their website and titled "Time to Get Even Lazier," Tom wrote, "We're hoping to be like 'I Love Lucy' and air 10 times a day on 'NPR at Nite' in 2075."

The Magliozzi brothers sat down with Steve Kroft for an interview with "60 Minutes" in 1995:

They're hilarious. I'm going to miss them.

Even though these two actually made a friend of mine cry when she called in, I'll miss them.

I'm really going to miss them, it's always been one of the most entertaining shows on radio.

I hit college in the Boston area in 1979 and haven't stopped listening to them since. True radio icons (their cartoon show a couple of years ago was a bit of a stretch, though). Live long and prosper.

[Henri_Rochard]
