|Official name:||Grumpy's Glock 17|
|First Appearance:||The Dark Knight|
In the vault, Grumpy learned that Happy had killed his accomplice on the roof after they had finished their task, under the order of the Joker. Grumpy revealed that their boss had told him something similar, afterwhich he shot Happy as he turned around to face his attacker.
As they gathered the duffel bags full of money Grumpy aimed his gun at "Bozo", who was the Joker incognito, believing that the Joker told "Bozo" to kill him as soon as the money was loaded. He never got to kill his "accomplice" since the Joker's bus driver backed a school bus through a wall, knocking Grumpy down and killing him.
