Ash : Don't touch that please, your primitive intellect wouldn't understand things with alloys and compositions and things with... molecular structures.

[after Ash chops up Evil Ash with a chainsaw and throws him into a hole]
Evil Ash : You'll never retrieve the Necronomicon! You'll die before ya get it!
Ash : Hey! What's that you got on your face?
Evil Ash : Huh?
[Ash throws dirt on Evil Ash's face]
