Barbary-Coast Bunny is a 1956 Warner Bros. Looney Tunes cartoon short directed by Chuck Jones and written by Tedd Pierce.
[2] Bugs is tunneling the cross country to meet his cousin Herman in San Francisco, only to run head first into a large nugget of gold.
However, when Nasty Canasta bangs his fist on the table in glee, this causes the ball to bounce and land into a knothole on the piece of wood, getting Bugs even more.
Bugs spins the revolver's cylinder like a slot machine and a mass of coins inexplicably pours out the gun's barrel.
As Bugs departs with all the casino's funds and more, Canasta dumbfoundedly looks at his pistol, then pulls the trigger in an attempt to make coins pour from the barrel.
