I did something like this a couple years ago. I "married" an obviously fake girl I created on Facebook. My ads internet wide quickly switched from "singles" ads to mortgages and retirement ads (with a smattering of child education savings thrown in). A couple months later I "divorced". That brought on the lawyer ads, and a fresh onslaught of singles.
I've been Facebook free for a while now, but the screen captures I grabbed and posted while doing this provided a lot of amusement for my friends.
