Origin of Kashruth
A dialogue while Moses is at the top of Sinai:
G-d: And remember Moses, in the laws of keeping Kosher, never
cook a calf in its mother's milk. It is cruel.
Moses: Ohhhhhh! So you are saying we should never eat milk and
meat together.
G: No, what I'm saying is, never cook a calf in its mother's milk.
M: Oh, Lord forgive my ignorance! What you are really saying is
we should wait six hours after eating meat to eat milk so
the two are not in our stomachs.
G: No, Moses, what I'm saying is, don't cook a calf in it's
mother's milk!!!
M: Oh, Lord! Please don't strike me down for my stupidity! What
you mean is we should have a separate set of dishes for
milk and a separate set for meat and if we make a mistake
we have to bury that dish outside....
G: Moses, do whatever the heck you want.......
