 Foxy Grandpa s boys attempt to play a practical joke on him by putting a bucket of water over his door and connecting it with a string to the door knob. While they are away Foxy Grandpa changes the string from the door knob to the door bell. The boys return, pull the bell, and give themselves a ducking, while Foxy Grandpa looks on with twinkling eyes from a corner of the window. Excellent comedy, well worked out.
