Haha, I'm glad I never did this.
The thought that the umd didn't belong in the case never crossed my mind. It looked like it belonged in there, so I didn't touch it. Come to think of it though, it is somewhat misleading. They should put giant warning labels on the front of psp games from now on since so many people have done it
At least you didn't attack it with that knife Frisky

You'd be buying another game right now if you did.
EDIT: Hey, you said it before I could Cess :/
