They may be presenting pros but even Ant and Dec fluff their lines from time to time.
And in this blooper reel from last year's (2016) show, we see just that.
The pair were attempting to introduce celeb camper Wayne Bridge to the latest bushtucker trial.
Hosts Ant and Dec welcomed Wayne to the trial clearing before trying to explain the task to him.
But Dec really couldn't get through the one relatively simple line.

"Down this ladder is the panic pipeline which is made up of a series of flooded chambers," is what Dec was trying to say.
"I'll put you down that ladder in a minute, come on, I want to get out of here" laughed Ant after Dec's failed attempts to read the sentence.
He then asks: "Shall I do it?"
Eventually Dec does nail his line, declaring "smashed it" before throwing his cue cards in the air and walking off.
I'm A Celebrity continues nightly on ITV with Ant and Dec.
