Genesis 3

Lo and behold, it turns out that God had decided to make snakes along with all the other animals. Not just any snakes mind you, but talking snakes. So, eventually one of these talking snakes decides to talk to the woman and convince her that God is a filthy liar, and that eating from the tree of knowledge actually won't kill anyone, but will instead only allow them to know the difference between good and evil. As it turns out, the serpent is actually telling the truth and God was in fact lying through his immaculate teeth, but we're still supposed to consider the serpent a villain. Okey dokey then.

Anyway, the woman decided to not only eat, but also rope her husband in as well, and thus they both learned the horrors of knowledge: Suddenly, instead of gallivanting around in the buff all over the garden, they decided they shouldn't really be seeing each others' naughty bits. Not only that, they began to suspect this whole naked people in a garden thing was really just a way for God to make some extra cash with a webcam peep show, and thus decided to start hiding themselves from God. Of course, this made God and his accountant very angry, so he came down to see what the deal was.

Upon being confronted by God, Adam immediately rats out his wife, and the wife blames the snake, who by this point has escaped with God's porno to a knothole in the Tree of Life for a little alone time. In response, God curses Adam for being stupid enough to listen to his wife, and curses his wife for being a disobedient bitch.

Then, to make matters worse, God dispatches a couple of angels with giant swords to keep Adam and Eve (the wife's name is Eve, by the way, although we didn't find that out until a couple of verses ago) from eating from the Tree of Life, which supposedly would make them live forever. However, since God has already been shown to be something of a fibber, the Tree of Life more than likely would have just given them herpes or something.
