Harry Hill says the producers at 'You've Been Framed' are inundated with "sex videos".
The 55-year-old comedian has narrated the popular entertainment show - which features hilarious home videos which they pay the creators £250 for - since 2004, and he's revealed that there are several "fakes" and x-rated clips which they have to dispose of.
Harry also suggested that he's contemplating leaving the programme after more than a decade providing giggles for families at teatime on Saturdays.
He told the Daily Star newspaper: "I don't get to see the long list but I know there are a lot of fakes - and a lot of sex videos.
"I've been doing that show for 15 years now.
"Do you think that's enough? Maybe I should call it a day."
Last year, the funnyman revealed show bosses have a difficult job of updating previous episodes because they have to take out mentions of celebrities who have passed away, and those arrested as part of Operation Yewtree, a police investigation into sexual abuse allegations.
He said: "It happens increasingly that the person I'm referencing has died.
"And they had to cut out a whole lot of references after all those people were arrested as part of Operation Yewtree."
Despite the difficulties, Harry - who followed on from Jeremy Beadle, Lisa Riley and Jonathan Wilkes in the role - said he was happy to carry on in job for as long as bosses and fans want him there.
He added: "God knows how many episodes I've done - thousands and thousands. I'll keep doing it while they want it."
Meanwhile, his latest gig is hosting the upcoming series of 'Junior Bake Off' with 'Great British Bake Off' judge Prue Leith and former contestant Liam Charles.
Harry recently confessed his new gig has made him "more nervous" than any other show.
The 'Harry Hill's Alien Fun Capsule' host found it tough asking a tent of nine to 15-year-old aspiring bakers questions about a subject he "didn't know anything about".
He said: "I was very nervous. It's 10 kids and you have to talk to them and ask them about stuff that I don't know anything about.
"I was more nervous than my other TV shows as I work with a script normally.
"But I got a lot out of it as well. And I started to relax when I watched it back.
"It dawned on me how to play it. Plus, there were a couple of children who really made me laugh."
