- The scene with the snowglobe of Acme Labs falling and breaking parodies the beginning of Citizen Kane.
- Snowball parodies the title character of Citizen Kane when he rules the world and Pinky parodies Kane's wife, playing with puzzles and being the wife (or assistant in this case) to the power-hungry guy.
