Highest, Fastest, not quite the strongest

Having look through my database for some interesting games, I began to wonder who was the highest rated player to get mated in 5 moves, in a proper game. Finding the answer was not quite as simple as it looked, as there were a few examples where strong players clearly threw the game in a very obvious manner (An example of this was 1.f3 e5 2.h3 Qh4+ 3.g3 Qxg3#)
So the game I have chosen may not be the absolute record holder, but it at least looks plausible (if a bit weird).

BTW, if you are looking for games that end Mate in 6, then take you pick from vast number of people who walked into 1.e4 c6 2.d4 d5 3.Nc3 dxe 4.Nxe4 Nd7 5.Qe2 Ngf6 6.Nd6#
