This is The Random User, a mouse and robotic finger that wheels itself around frantically clicking its way across the internet. It looks like it could also double as a sex toy.

Of course explaining how it managed to enter your name and credit card info is entirely up to you.
PROTIP AMATEURTIP: Mumble something about Skynet being out to get you.
Keep going for a video of the clicker in action.
