Noah was the first drunken preacher of righteousness.
God ... spared not the old world, but saved Noah the eighth person, a preacher of righteousness, bringing in the flood upon the world of the ungodly. 2 Peter 2:4-5
God told Noah he was going to send a flood to drown everyone on earth. He didn't ask Noah to warn anyone by preaching. And Noah didn't say a word until after the flood, when he cursed his grandson and all of his descendants with slavery because his son saw him drunk and naked in his tent.
And God looked upon the earth, and, behold, it was corrupt; for all flesh had corrupted his way upon the earth. And God said unto Noah, The end of all flesh is come before me; for the earth is filled with violence through them; and, behold, I will destroy them with the earth. Genesis 7:12-13
Noah ... drank of the wine, and was drunken; and he was uncovered within his tent. ... And Ham, the father of Canaan, saw the nakedness of his father. ... And Noah awoke from his wine, and knew what his younger son had done unto him. And he said, Cursed be Canaan; a servant of servants shall he be unto his brethren. Genesis 9:20-24
