Cuffed to the wall
How about this challenge! I am cuffed to the wall with two pairs of HINGED cuffs. It is impossible to escape, right? Because I can not even twist my wrists, and there is no way I can reach the other hand with my fingers. Well, of course, I will show you how I escape from this. It is VERY hard, do not try this at home if you are alone. You will need someone to rescue you in case you fail!
