I'm a guy, so there is a chance that there will be a very minor case of extreme bias.
This episode is, without a doubt, as hilarious as it is a cock-tease. I enjoyed every minute, even the very confusing end. There is no plot or point to this. It's pretty much fanservice. But then again, there's never anything wrong with that, is there?
All in all, if you are into this kind of thing, and you've got nothing else to do, then go into this with a big grin on your face, and I can guarantee that you'll end this with an even bigger grin (and if you're sensitive to it, a gun in your pocket).
