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 hell you want.......
