This challenge has to be done outside and you have to bring along a chain and a lock. Perhaps when you are creative, the handcuffs might work as well.
- Step one: hide the keys somewhere as exciting as you dare. An open area near a road and/or a lamppost.
- Step two: walk away for a minute or two and make the route as exposed as you dare.
- Step three: get naked and use the chain and lock to lock your clothes away around a tree.
- Step four: enjoy the sneaking while being naked up and down to retrieve the keys.
I hope you like this dare.
