I found this to be a treat to watch as my girls invented the Doctor game. Two people get twisted up like so,
While the doctor steps aside.
The two twisted call out, "Doctor, doctor!" In which she replies: "Yes?" And then she solves their problem by getting them unstuck. Novel isn't it?
When the problem is solved, you raise your hands in the air and shout, "You did it!" Game over.
Pure joy watching it.
