Hmm...
The animation's hilarious. However, I'm getting the feeling that the game's programming just randomly puts the weapons in one of the cups, so it's up to the player's luck whether you're right or not. I could have the same amount of fun flipping a coin fifty times.
The idea isn't bad, but it's not really a game like this. Two suggestions: 1) Make it like a real cups game. Before Saddam starts spinning them around, you should be shown under which cup the weapons currently are. 2) Push up the framerate big time. Two or three times as many fps as there is now. This is so you can actually try to keep your eye on the cup with the weapons. Right now it's just a couple of cups in various positions.
You could put in different difficulty levels, making the cups spin faster the more the player gets right. Maybe some more funny animations.
