In the Special Edition DVD, when you play the film, at first a film called "Dentist On the Job" starts playing, and it goes up until the end of its opening credits, then you hear someone saying that they put in the wrong film. The film stops, a quick reel change slide is put up, then the real movie starts.
On the Regions 2 and 4 DVD's (Europe and Australasia) release, the end credits are extended to three minutes (rather than 20 seconds) of a black screen with the intermission music.
In the opening credits, there are a pair of Chinese symbols which translate to "drink tea".
