Christian totally misinterprets the task
Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!
Christian arranges for 'a doctor' (actually an actor wearing a costume) to be waiting for Mark outside the shed. He then feeds Mark healthy foods, gives him (unspecified) pills, and makes him run on a treadmill. He appears to have misinterpreted the task as being about making Mark healthier, possibly due to his dyslexia, but Lasse places him second for the surprise anyway.
