I can see that as a gag in a Jackie Chan movie.
ROBBER: “Gimme your money, or I’ll shoot!”
CHAN: “You won’t shoot. Your gun is jammed.”
ROBBER: “What? No it’s not!”
CHAN: “Here, let me help.”
CHAN disarms the ROBBER, drops the magazine, pulls back the slide, lets the bullet fall, reinserts the magazine, and releases the slide, then places it back in the ROBBER’s hand before he even has time to react to it being taken from him.
CHAN: There. Say the thing about the money again.
The ROBBER looks at CHAN, looks at the gun, looks at CHAN again, and runs away.
