Mouse

[Becky]

While most people dont want to see a mouse running around in their home, they typically dont have a problem seeing one sitting by their computer. This is because, along with the keyboard, the mouse is one of the primary input devices used with todays computers. The name comes from the small shape of the mouse, which you can move quickly back and forth on the mouse pad, and the cord, which represents the mouses tail. Of course, if you are using a wireless mouse, the analogy does not work so well.
All mice have at least one button, though most mice have two or three. Some also have additional buttons on the sides, which can be assigned to different commands. Most mice also have a scroll-wheel, which lets you scroll up and down documents and Web pages by just rolling the wheel with your index finger.
Early mice tracked movement using a ball in the bottom of the mouse. This mouse ball pushed against different rollers as it moved, measuring the mouses speed and direction. However, now most mice use optical technology, which uses a beam of light to track the mouses motion. Optical mice are more accurate than roller-based mice and they have the added bonus of not getting dirty inside.
A plurality of plurals
When you refer to more than one mouse, you can call them either mice or mouses, since both terms are acceptable. However, mouses is technically the correct version since mice is the plural form designated for living creatures. Still, most people have a hard time saying mouses, which is why mice is more commonly used.

[Ernesto]

A [sneaky little bastard] that can only be seen out the the corner of your eye as it jumps into your food cabinet. Upon inspection, it is no ware to be found until you open your Costco size industrial box of Lucky Charms, and [there he is]. Pissing and shitting into your priceless box of little rainbow gems. Pissing you off so much that you willingly [camp out] in your kitchen with a 12-gauge, just waiting for that little mother fucker to come out. Of course he doesnt come out until after you have got up and put your gun away, you walk back into the kitchen and there he is, shitting on your floor while he laughs at you. He will always be watching you. Laughing. Judging.

The protrusion into our dimension of a [vastly] [hyperintelligent] pandimensional being. The [mice] run the Earth, and it was they who paid for the Magratheans to build it.

[Sarah]

A little [hairy bastard] that out-wits every means of capture and continues to [make noise] in the wall over night or while [Im taking a shit] in the bathroom. Probably watching me.... what a fag
