Today we're celebrating 20 years of Moncrieff on Newstalk.
The show went on-air on May 24th in 2004 and since then has covered every conceivable topic you can think of - and some you never even considered.
On Friday's show, Sean said he never wants to speak of it again.
"Today is May 24th 2024 - which is not a great revelation, really - but May 24th 2004 was the day I did my very first show for Newstalk," he said.
"So this is a special 'I can't believe he's not fired' edition of the show.
"I want to celebrate it in the most Irish way possible: that being that I'm going to tell you this now and then we're never going to mention it again.
"Thank you very much," he added.

Others have been reminiscing on the last two decades:
Today marks the 20th anniversary of Moncrieff. The hit radio show with @SeanMoncrieff. When I first heard I would be working with him, I was like “That guy!”. Sean is too humble to make a fuss so this pic taken by CC in Brussels in 13 will have to do. @NewstalkFM #Moncrieff20 pic.twitter.com/qrEnX4OomI

Happy 20th Newstalkiversary @SeanMoncrieff. I learned an awful lot as a researcher on your show...vital things like how to get an alpaca across the Ploughing Championships site and that I should NOT drink JD&Coke 🤢.
Dya remember that time we shaved you live on air? Genius. pic.twitter.com/uObv2DLFqZ— Jess Kelly 👩🏻💻 (@jesskellynt) May 24, 2024

Happy 20th anniversary to Moncrieff on Newstalk. When I first saw @SeanMoncrieff blow a condom up over his head on The End, I knew he was the man for me.
For 20 years on @NewstalkFM, he's taught me how to learn, and he's taught me how to love.
Here's to 20 more!#Moncrieff20— Finbarr O'Sullivan (@handsomepostie) May 24, 2024
Happy Moncrieff Day, everyone!
