Carl Kasell, judge and scorekeeper of NPR's hit game show "Wait, Wait...Don't Tell Me!" is retiring this spring, NPR announced on Tuesday.

Kasell, who worked for NPR's Morning Edition for three decades, said he enjoyed working for the news quiz show.

"It was loads of fun and gave me a chance to meet and talk in person to the audiences that I felt I had known for so many years on the air," Kasell said in a statement. "I can honestly say I am the luckiest man around to be able to have worked at a job I love for so many years. It's truly been a joy to me."

Kasell joined "Wait, Wait...Don't Tell Me!" in 1998. Prior to that, he did newscasts for NPR's Morning Edition from 1979 to 2009.

NPR said that after Kasell retires, he will still do voicemail greetings for the show's winners and "occasionally appear on the program." Already, more than 2,200 people have Kasell on their voicemail, NPR said.

To answer some questions: 1. Carl will still be recording messages for our winners. 2. Yes, he is just as charming and dapper in person. — waitwait (@waitwait) March 4, 2014

NPR is inviting Kasell's fans to leave him a voicemail message at 1-888-924-8924. No replacement has been named yet, according to Peter Sagal, host of "Wait, Wait...Don't Tell Me!"

In re: a FAQ. We haven't decided on a replacement, yet. Hardly thought about it. Want to take our time, not go for a rebound host. — Peter Sagal (@petersagal) March 4, 2014

Retirement will give Kasell more free time, according to Sagal.
