Genesis 9:21 tells us about Noah becoming drunk, and HE (Noah) was uncovered within his tent.  It makes no mention of Noah's wife being uncovered and naked in the tent and having sex with her son Ham.  Genesis 9:22 then proceeds to tell us that Ham, the father of Canaan, saw the nakedness of his father, and told his two brethren without.  If Genesis 9:21 was left out of the Bible, then I could see how both you and Patti C. came to the conclusion that the "father's nakedness" described in Genesis 9:22 might possibly be the nakedness of Noah's wife from reading Leviticus 18:8...."The nakedness of they father's wife shalt thou not uncover; it is thy father's nakedness." However, we are not supposed to add or leave out verses from the Bible so that's why I still disagree with the idea that the father's nakedness was Noah's wife having sex with Ham, her son, because the nakedness of Noah portrayed in Genesis 9:21 is still the same nakedness of Noah portrayed in Genesis 9:22.
