user86: There seems to be a pretty nifty attack for White after  1.e4 e5 2.Nf3 f6:
[FEN ""]

1.e4 e5 2.Nf3 f6 3.Nxe5 fxe5 4.Qh5+ g6 5.Qxe5+ Qe7 6.Qxh8

I've played as White with this opening several times, always to my advantage (usually Black panics and plays 4 ... Ke7, soon after which he finds ample reason to resign).  But once someone played as shown above, and went on with
6. ...     Nf6,
  etc.

to try and put my queen on the spot.  Presumably he intended to follow up with moves such as ...b6, ...Bb7 or similar, ...Nc3 or similar, ...O-O-O, and then ...Bg7 forcing Qxd8.  Since it was a blitz game, best play was not made, and he made a mistake allowing my queen to escape, but it got me thinking.  Is there some way Black can recover from 1. e4 e5 2. Nf3 f6?
My question especially regards 1. e4 e5 2. Nf3 f6 3. Nxe5 fxe5 4. Qh5+ g6 5. Qxe5+ Qe7 6. Qxh8 (as shown above) - is there a way to trap White's Q?  Or is 3... fxe5 simply a bad move?  Should 2... f6 be avoided altogether?

user75: No, the Damiano Defense does not lose by force so it's not a bad opening.
If you analyze it with a computer you won't be able to find a variation that wins for white against best play.
After 1.e4 e5 2.Nf3 f6 3.Nxe5, playing 3...fxe5 will lose for black but playing 3...Qe7 will hold the game. For example check out the game Fischer vs McGregor, 1964 (here's a version with commentary on YouTube), which ended in a draw.

user12: This opening is also known as the Damiano Defense and it is just bad.  
In the line you gave, where black plays 6... Nf6, white's best plan is to play d3 and Bg5.  Black can't move the bishop because it is pinned (so the queen can't be trapped until black castles).

user258: White has a forced win of a bunch of material after either 4... g6 or 4... Ke7, but if you're into silly "psychological" justifications for moves, you could argue that 4... Ke7 makes White think a little harder to find the win, while Black can prep it.
4. ... Ke7 
5. Qxe5+ Kf7 
6. Bc4+ d5
7. Bxd5+ Kg6
8. h4 h6

This is the only line that leaves White with an overwhelming advantage; for instance, one game between relatively weak players continued:
8. Qg3+? Qg5
9. Qxc7 Ne7
10. Qd6+? [h4!] Kh5

(Feng-Sloan 2010)
After which Black looks hopeless... 

...but is actually just bad.
However, you may already know that if White plays correctly up to 8 ... h6, they have a killer 9th move that picks up material. Here's a diagram as an exercise for the reader:

user63: After 
1.e4 e5 2.Nf3 f6 3.Nxe5 fxe5 4.Qh5+ g6 5.Qxe5+ Qe7 6.Qxh8 Nf6

with ideas of trapping the queen, 7. d3 followed by Bg5 or Bh6 and there won't be any issues getting the queen out, e.g.:
7.d3 d5 8.Bg5 Nbd7 9.Nc3 b6 10.0-0-0 Bb7 11.e5

Black can try to minimize the damage after 2...f6? with something like 3.Nxe5 Qe7
You aren't losing the exchange any more, but you've still destroyed your position with ...f6.  
2... f6 should be avoided.
