ITV's Bear Grylls: Mission Survive put footballer Alex Scott, Dancing On Ice judge Jason Gardiner and actress Samantha Barks through the mill in the tough final.
Having to drink their own urine and endure a 'rectal rehydration' wasn't enough. The three finalists had to eat a fish eye. Yuck.

The sound of the eye being crunched in their mouths was a bit much though according to viewers who posted on Twitter.
