It's still cool. I could do that for hours. Thank heavens for my wife, who keeps me from doing it for too long. I wouldn't mind seeing an Osama version, or maybe one with my ex wife.
The trick is to let it progress naturally and give it only MINIMAL assistance. I've kept this Flash game going for HOURS with just the barest hint of help from me.
I wish they offered you a choice of who you had doing that. Considering you can use your mouse to grab the person and sort of slam them around, I wouldn't mind if they made any number of people as the "model" in this one.
