There are four characters: a director, a cook, a passerby, and a doctor. The cook stirs an imaginary bowl of gravy.
The passerby walks up and says, "Whatcha doin'?" The cooks says, "Making gravy."
Passerby: "Can I try some?" "Sure!" Passerby sticks a finger in and tastes it. Passerby then begins to choke and stager and eventually die.
The cook runs and grabs a doctor. "Doctor, Doctor! She just ate some of my gravy and fell over! Is she dead!?"
The Doctor, walks over checks her pulse. Picks her arm up and lets it fall, then announces "Yes, she is dead." The director yells "CUT!" and proceeds to tell them that the scene was too (blank) and needs to be more (blank). Then you just do the whole thing over in different styles. Faster (do it in three seconds) Slower (in slow-motion) Fung-Foo style, cheerleader style... have fun with it!
