Which single task, across all series, would YOU most like to have taken part in.
It can be any task. Solo, team, etc. This includes the final 100 second task on stage but EXCLUDES bringing in an item task. So no, you can't put your wedding ring up as a prize. But you CAN sing to Rosalind (Just be warned, she is a fucking nightmare.)
Which task would you, yourself, most like to have taken part in? You would be the 6th contestant in that singular task. So if there was a 3-man team and a 2-man team in a task, you could be on either team. Making it 4 vs 2 or 3 vs 3.
