Feel I can reveal two of my very favorite shooters..
I have used them both with great deal of success on my wife when she is just about to go out of the shower.. Best effect is achieved by placing it in the freezer (for a very short time) or the refrigerator prior to the attack ;-)
The blue one is equipped with an extra annoying feature, a flute in the rear end. For that reason it's my preferred choice.. but it goes a little to the right, so I should probably bring it to a toysmith some day.
Can't beat the price for ammunition btw
