The 52-year-old actor appeared on The Ellen Show which was being hosted by Jennifer Aniston that he has to volunteer at his kids' soccer matches and it usually takes half the game until he is recognised.
Referring to his referee kit, the dad-of-three said: "I have to wear that. Look at that, I am ready to call off-side at any time."
Then he continued: "I usually get through half of the game before one of the kids on an opposing team is like: 'Are you the elf? What are you doing here?'
"But they're in the middle of the game and they'll stop and be like: 'He's the elf,' and the coach will be like: 'Shut up, GET THE BALL'."
Back to mimicking the child, he said: "But the elf is..."
Ferrell agreed with Aniston, when she suggested: "So it's like a distraction so it's almost an advantage for your children."
It seems that Ferrell's own children aren't as flabbergasted by his soccer appearances - after all, to them he's just 'dad'. Sorry Will.
They're probably not phased by it because - along with the rest of us - Ferrell's children are used to watching Elf each Christmas. He actually uses it as a way to calm them down when they're hyperactively unwrapping their presents.
Speaking to E! News, he said: "It's always chaotic. There's a lot of screaming and yelling and complaining as to when they get to open their presents... I think they each get way too many presents each.
"We have three boys. And [the presents] are opened in 12 minutes. [So] I force them to watch Elf 10 times, 10 straight times. It's a marathon, and then you get to open a present after."
So we're kind of hoping he's joking - even though an Elf marathon wouldn't be the worst thing in the world, 10 times, seriously?
Especially considering that the final scene is something of a real tearjerker. So much so that it even sets Ferrell off.
In an interview with Rotten Tomatoes, he said that, even 16 years since the film's release, he's been known to get choked up during the poignant scene, which sees a crowd of people singing 'Santa Claus Is Coming To Town' in Central Park.
Will said: "When Buddy is in the back of the sleigh and everyone is singing in Central Park and there's enough Christmas spirit to get it lifted off, I'm like, 'Oh, I can't let everyone see me cry here at my own movie'."
To be fair, Will Ferrell can do whatever he likes.
