The Damiano!

So I had people over last night and one of them wanted to play chess. The game went

1. e4 e5
2. Nf3 f6?!
3. Nxe5 fxe5?

and then a few unimportant details because the game is lost here. He went for losing the exchange rather than getting chased around. His remark afterward was that he didn't know openings, and I guess if you play the Damiano, that's the one time a beginner could use a hint about openings. Just play 2. ... Nc6! Beyond that, no point in knowing openings at that level.
