The gruesome challenge knocks him off his feet – literally.
ITV has released an advance look at tonight's I'm A Celebrity 2020 Bushtucker Trial, in which Olympic champion Mo Farah takes on the critters of Fort Locks.
The challenge utilises a classic I'm A Celeb trope by asking its unfortunate participant to blindly stick his hand into a wall, where all manner of creepy crawlies await within – nobody tell Paul Burrell.
As you would expect from an athlete of his caliber, Farah gives it his all but Ant and Dec can't help but giggle as he shrieks at the nasty surprises they have in store.
Check out the clip below, in which the gold medallist is tasked with retrieving keys from one side of the wall, which unlock the stars hidden in the other side.
In perhaps the cruellest moment, Dec assures Farah that he can go "nice and slow" only to retract that comment, saying "not that slow" as Farah is bombarded with what appears to be either fish guts or animal organs.
The impact takes him off his feet, but he quickly recovers to resume his hunt for stars – fans will have to tune into the full episode on ITV tonight to find out exactly how he gets on.
