- If there are two rabbits in an area, they will...do what rabbits are known for. And shortly thereafter, with a 'Pop!' there will be three rabbits.

- Even better in the Redux rerelease on Steam where this now gets you an achievement.
- Some of the Ice Cream Koans you get when you find a fortune cookie:Man who stand on toilet, high on pot.
- Lo Wang's seemingly endless collection of penis jokes around his name. Even the video of the remake has a moment where he answers the phone with "You've got Wang!"
