anybody know this?? i need the name!

wonder if anybody heard this "game" before....
the story goes:
5 people got stranded in the mountain, one of them died...
the rest of them found a cabin but weren't able to keep warm, and not falling asleep..
one of them remember a game he read before and asked everyone to stand in each corner of the retangular cabin...
the person A in corner 1 walk up to person B at corner 2 and pet his shoulder, then person B will go pet the shoulder of person C, then C to D.....etc...
they kept circulating around the cabin until the rescuers found them... after some days...
they asked them how they survived, and was shocked by the game because the game is just simply impossible...with only 4 people...


and just in case anybody wonders....here's explaination:
1(A) --> 2(B) -- 3(C) -- 4(D)
1(X) -- 2(AB) --> 3(C) -- 4(D)
1(X) -- 2(A) -- 3(BC) --> 4(D)
1(X) -- 2(A) -- 3(B) -- 4(CD)-->
1(DX) -- 2(A) -- 3(B) -- 4(C)

X is a empty corner

if anybody know the name of the game, please tell me!! thx
