Ponder This Challenge:

This month's challenge is a famous chess problem. To enjoy it, don't cheat by looking for a solution over the Internet.

What are the five moves in a chess game that starts with the white king's pawn moving 2 squares ahead (e2-e4) and ends with a black knight capturing a white rook leading to a check-mate?

Update 02/03: The games starts with all pieces in their regular place; and by five moves we mean 5 white and 5 black.
