Okay, evidently I am grossly stupid! I was answering in all seriousness and, looking at the original post, I see no other way, obvious or not, that it can be interpreted unless you count each move by black and white separately in which case the answer is 13.
I really don't see what I am missing that is so obvious, enlighten me please (preferrably without the sarcasm if at all possible)!
Sorry, I see you were replying to Bowman and not me. Maybe I'm not grossly stupid, I just can't read!!
With only moving pawns I don't see how it can be done any quicker since you need to get two pawns down to the 6th. Now, with the loser moving any piece maybe there is a shorter help mate involving promoting a pawn, I'll look at that.

Here is your latest offering (dated April 17, almost 3 months ago), something that even bobbob1056th himself would no doubt be proud of:
If you're at a loose end one evening and wish to pass some time, set up a chessboard and simply do the following, either alone or with the aid of a friend:
Play just 3 moves into a game (each side). Put the pieces back onto their starting squares again and play another 3 moves into a different game. Repeat until you have made all the possible combinations of moves, reaching all positions.
If you find that doesn't kill sufficient time, try it again using 4 moves...
Although it does not resemble a puzzle, it certainly invokes a few question marks!
