At first glance, it looks like someone's got his hand up a mini-skirt. Take a closer look, and there's really a mouse pad inside the skirt.
Unfortunately, since I only found this one a Japanese-only online store, I don't know how much it costs. I did notice that in 2006 Axe had a promotion for their AxeFantasy site using these pads.
I hate to admit it, but I found this hiliarious, but at the same time, somewhat disturbing.
