ok....
now I can't answer this question as well as a lot of people might, but I can fill you in a bit prime.....
there is a novel, I believe, but damned if I can remember the title or author....might even be a film, probably was made into one...
anyway,,,, it is a bit of a sci fi thing, in the future..., and food is scarce... they come up with a food thingy called Soilent Green.... anyway.... what it turns out to be is a food made from dead people, basically making anyone who eats it a cannibal, but they don't exactly make this known to people....however, it is found out eventually...
for a GOOD LAUGH there is a film called Drop Dead Gorgeous, and it is funny as hell, and there is a scene where a girl in a beauty pageant does a reenactment of the whole "soilent green is people!" scene..... needless to say, she doesn't win....
hope I at least made sense of the whole thing...
