What color is your DS? Not that you should have to buy a pink DS, but it might have eventually made him give it back. Of course, then you are stuck with a pink DS.
Trick number 2 would be go to buy Nintendogs with his favorite dog. Just for him. He'll enjoy it for a bit. (I liked the frisbee throwing.) Then in a couple days, get tired of it. And you can get your DS back. Of course then you are stuck with a pink DS and a copy of Nintendogs.
Lastly, you could tell him he either coughs up some money for his own DS, or else you'll be forced to hock your engagement ring to pay for a new DS. And he might have to buy you a new one!!
Fortunately for me, daughter 2 steals daughter 1's DS. It's a pink DS, of course. Mine is not. ;)
Torturing the numbers. Hear them scream.
