If you spent any time on the internet in the early 2000s you're probably familiar with the heart-stopping K-Fee advert, which goes from soothing to terrifying in under 20 seconds - familiarise yourself here:
Well, now someone has tracked down the bloke who played the zombie and he's a lot less scary behind the make up.
YouTube channel Rhys Productions 11 found the zombie - also known as Brad Johnson - who revealed how he managed to get involved in the project.
Speaking to the YouTubers Rhys and Jamie, Johnson said he actually ended up in the advert because a friend of his was the cinematographer.
The pal had first attempted to use puppets to create the scare but after deciding it didn't quite work, he reached out to Johnson and his brother and asked him to get involved.
He said: "We were in LA and were shooting at a studio because they shot all the other stuff before we got there. We just shot our stuff in front of a green screen.
"Yeah, so we went to the studio, sat for about four hours in makeup."
Opening up about the reaction the advert received, Johnson said: "We heard a lot of people were complaining because people were having heart attacks and problems with kids - so I think it got banned in some places.
"It's so funny because it was just a quick little gig we did one day, our friend called us and we went and did it really quick and it never died.
"I've seen it on The Simpsons where they're watching the commercial, talk shows - it went all over the place.
"I thought it was funny, I'm always down to prank people and give them a good little jump. It was funny because with all that makeup on, just walking around, anyone that saw us, just driving past, would have a little panic attack."
But despite being viewed by millions, unsurprisingly Johnson said he doesn't often get much attention from being in the advert.
He added: "Of course I showed people, but nobody ever recognises me from that commercial.
"I didn't get any fame from it, there's only a few people who are, like, die-hard 'zombie people' who have tracked me down.
"It's cool, it's nice."
So there you go, turns out all your childhood nightmares were for nothing because he's actually pretty sound.
