What is the specific content of the joke that the Zen master ordered a hot dog in the American movie "Foreseeing the Future"? It is not detailed in the film.

The Zen master said, "Give me a hot dog with everything."

The joke is that Buddhists have never eaten hot dogs, thinking that hot dogs are made of dog meat, so they want a hot dog, all parts of the dog (legs, back, etc.).

If you think too much, you will make a joke sooner or later.
