The Sprinkler Sprinkled (1895)

A gardener is watering his flowers, when a mischievous boy sneaks up behind his back, and puts a foot on the water hose. The gardener is surprised and looks into the nozzle to find out why the water has stopped coming. The boy then lifts his foot from the hose, whereby the water squirts up in the gardener's face. The gardener chases the boy, grips his ear and slaps him in his buttocks. The boy then runs away and the gardener continues his watering. Three separate versions of this film exist, this is the original, filmed by Louis Lumière.

Unfortunately the movie The Sprinkler Sprinkled is not yet available on HBO Max.
