Oil's Well is a 1929 short animated film starring Oswald the Lucky Rabbit and produced by Walter Lantz Productions.
He then moves the car to a condo window of a certain floor and attempts to serenade Kitty with a trombone.
In response to this, Oswald pushes the grumpy dog back and picks up Kitty using the slide of his instrument.
He subsequently retrieves a large cannonball from his pocket and comically shoots the oversized projectile from his rifle.
Oswald catches it with his trombone and shoots it back, hitting the bloodhound, with a large, balloon-like bump on his head resulting from the injury.
The bloodhound then puts a tombstone, designated for Oswald, on the ground, and forces the rabbit to dig a grave.
