Celebrity SAS: Who Dares Wins pushes big names to their physical and mental limits, but recruit Jack Maynard's scared of something else entirely.
The 25 year old YouTuber looked repulsed as fellow recruit Katie Price snorted snot onto the ground as the hopefuls lined up for an early morning debrief.
They gathered and stood in a line before Ant and his crew of military hard men arrived.
Katie, affectionately named "Number Three" for the series, landed the group with a round of press-ups after she followed through on an order too early.
Jack, meanwhile, had opened up about his mental health struggles ahead of his SAS stint.
He took part in I'm A Celebrity...Get Me Out Of Here! in 2017, but pulled out after a string of historic homophobic and racist tweets surfaced, as well as the revelation that he had asked a 14 year old girl to send him nude photos online.
The girl did later say that he was 16 at the time and that she never felt "harassed."
He wrote: "Doing @sas_whodareswins was a huge huge huge decision for me to make.
"I was in a very low place mentally at the time & coming back to TV after previous experiences made it even harder.
"But, I knew the best way to help my anxieties and worries was to take them head on & really see how far I could push myself."
Jack continued: "Around the time of filming I was experiencing the worst anxiety I've ever had.
"I wasn't able to work, experiencing panic attacks, speaking to therapist and wasn't sure how I was ever going to get back to my normal self.
"But, with much thought we decided that maybe this show & the immense mental and physical challenge could be good for me...And looking back, it is one of the best decisions I have ever made!
"Thanks to the INCREDIBLE people involved with the show, the DS and my UNFORGETTABLE team mates, having come out I've found myself happier than I've ever been!"
