Ant & Dec's Saturday Night Takeaway will celebrate its 100th episode on Saturday night.
And ahead of the VERY special live episode, hosts Ant and Dec have been sharing their top moments.
Saturday Night Takeaway first aired in 2002 before taking a break in 2009. The show returned in 2013 and has got bigger each year since.
An audience of over 8 million tuned in to last week's new series opener, the 99th episode.
Speaking ahead of this weekend's landmark 100th show, Ant and Dec have shared their best hits.
Ant revealed: "The top one has got to be our Undercover on Simon Cowell. It was the first one we ever did - we flew to LA and auditioned for American Idol, which was really nerve wracking. Also the prosthetic make-up didn’t turn up so we had to do dodgy beards and stick-on earrings but it worked."
Dec added: Last year’s series finale in Disneyworld Florida. That was amazing. Doing our finale with the castle in the background was something we’d wanted to do for a long time and that’s definitely a top five moment.
"One of my favourite ever Get Out of Me Ears was Richard Madeley, when he had photographers coming around to his house to talk about doing a calendar. We made him take a shine to a photographer’s shoes and try them on, then dip his toe into the swimming pool to see how warm it was, still wearing the shoes. I don’t think I’ve laughed so hard in my entire life. He’s a genius."
Ant continued: "Michael Buble going across to the pub with Lewis Hamilton for the End of the Show Show because it was so different and memorable.
"[Also] Probably abseiling down the building for Ant Versus Dec. I love anything that involves heights and danger and potential death!"
Dec agreed: "I remember when we first abseiled down the building and as you went down you got to peer into all the windows and it was really interesting. I just remember thinking how messy some people’s desks were!"
Ant & Dec's Saturday Night Takeaway airs Saturday night at 7PM on ITV.
