Try to create this position from the beginning position in 4(not 3)moves. I found this task in one interesting book and I didn't solve it. May be you can. 

Does this count, or does black also have to move?

Black also have to move, but you found very interesting variant.

I'm pretty sure its impossible. I have a (possibly flawed) proof of that fact but it's kinda hard to explain it.
Here is beatiful solution to a similar possition:

I'm completely stumped.  Perhaps you're mistaken about what your book meant by 'four moves.'  'White to play and mate in 3,' for instance, gives black just two moves.

 I found the solution. Here it is but think may be you want first try to find it by yourself.

Genius!

AHA!  I don't think this really helps me in any way, but it sure was fun!  Thanks for the solution, Kingskiller.

Yes, I agree that it is very easy to create it in 3 moves. That's why I called topic "It looks easy". But if you add one more move it becomes much harder...

kingskiller has found the proper solution indeed.

hehehe. i couldn't find it. thanks! :)
